San Francisco (CNN Business) Two of San Francisco's wealthiest tech leaders clashed on Twitter over the best way to address the city's homeless problem. 
 
 Salesforce CEO Marc Benioff is pushing for a tax on San Francisco's largest companies to raise money for homeless efforts. Twitter and Square CEO Jack Dorsey is against the tax, and wants to let the city's new mayor, London Breed, come up with alternative plans. 
 
 "These tech CEOs, they need to realize if they want to do business in San Francisco and use all of our civic resources, and in some cases have gotten mid-Market tax breaks, then they should be more than happy to give a small amount — which is what it is for these companies — to help us focus on our number one issue," Benioff told CNN Business in a phone interview Friday afternoon. 
 
 Benioff is spending money to promote ballot Proposition C , which would tax large companies based in the city. The tax would vary, but come out to about 0.5 percent on businesses' gross receipts above $50 million a year. 
 
 It would raise up $300 million annually to address homelessness by building more housing, increasing mental health treatment, and adding shelter beds. That is double what the city currently spends a year on the issue. 
 
 Salesforce is the largest employer in the city, and Benioff, a San Francisco native, is very active in local issues. He has been a major donor to San Francisco and Oakland public schools, and recently helped raise $37 million for the Heading Home Campaign, which aims to get families with children off the streets. 
 
 "I want to help fix the homeless problem in SF and California. I don't believe this (Prop C) is the best way to do it," said Dorsey in a Tweet reply to Benioff on Friday. 
 
 I want to help fix the homeless problem in SF and California. I don't believe this (Prop C) is the best way to do it. I support Mayor @LondonBreed and @Scott_Wiener's commitment to address this the right way. Mayor Breed was elected to fix this. I trust her. https://t.co/EsxapfDvtI — jack (@jack) October 12, 2018 
 
 Benioff replied by asking for examples of how Dorsey has helped and what donations he's made. Dorsey called the question a "distraction" and said he wants to support Mayor London Breed's efforts. 
 
 Mayor Breed has come out against the proposition, citing concerns about oversight and accountability for how the money is used. There are also concerns it could lead to layoffs or cause businesses to relocate, Breed has said. Breed wants to know more about how it will impact the local economy. 
 
 "I do not believe doubling what we spend on homelessness without new accountability, when we don't even spend what we have now efficiently, is good government," said Breed in a statement. "I absolutely do agree business can pay more to address our homeless crisis, which is why I will lead the effort to do this the right way as Mayor, and I look forward to continuing to work in partnership with Marc and others do that." 
 
 In a statement, a spokesperson for Square said: "Homelessness in San Francisco is a humanitarian crisis. We support Mayor London Breed, Senator Scott Wiener, and Assembly member David Chiu's calls for a consensus response to homelessness, and we are eager to collaborate with City Hall, local organizations, and other businesses on a unified approach to this issue. Prop C is not that approach." 
 
 Benioff says he recently got a call from the mayor asking for $8 million to fund a new shelter. 
 
 "If she had Prop C, she wouldn't have to call for that money. It would already have been given to her. Seems pretty straightforward to me," said Benioff. 
 
 The debate mirrors a similar contentious battle in Seattle this past summer. The city had proposed a new corporate head tax to raise money for homeless service. Amazon led the charge to stop the tax from being passed. 
 
 San Francisco's tax could fare better. A local homeless advocate group raised the signatures to get it on to November's ballot. It has support from other large companies like Cisco, as well as Representatives Nancy Pelosi and Jackie Speier. And Benioff is ready to fight for it. 
 
 "I didn't realize until this morning that Jack Dorsey was not going to support it," said Benioff. "The question is how much is he giving back to our public hospitals and schools and to our homeless programs. The only way we're going to make our city better is if we tap the incredible wealth that it's generating." 
 
 Benioff, who says he talks to Dorsey regularly, has been paying to promote tweets supporting the proposition. 
 
 "I'm glad that Jack tweeted that because we need to have a pubic discussion about homelessness and how we're going to solve it." 
 
 Dorsey tweeted late Friday that discussions were under way. 
 
 "Marc and I talked on the phone. Also talked with Mayor London this afternoon. We're all talking now and aligned to fix this issue as fast as we can. Will keep everyone updated," he said. ||||| Add this Tweet to your website by copying the code below. مزید جانیئے

 Twitter and Salesforce CEOs bicker over who is helping the homeless more 
 
 The CEOs of two of the world’s most prominent tech companies got into an online spat on Friday over who was doing the most to address homelessness. 
 
 The Salesforce CEO, Marc Benioff, and Twitter CEO, Jack Dorsey, were tweeting at each other about a proposed tax on high-earning San Francisco businesses. It would redirect millions of dollars to help thousands of people who live on the streets, including outside the headquarters of both companies. 
 
 Benioff tweeted that he was in favor of the tax. Dorsey tweeted that he was not – prompting a displeased response. 
 
 “Hi Jack. Thanks for the feedback,” Benioff quipped. “Which homeless programs in our city are you supporting? Can you tell me what Twitter and Square & you are in for & at what financial levels? How much have you given to heading home our $37M initiative to get every homeless child off the streets?” 
 
 Benioff was referring to an initiative he is spearheading for homeless families. In May he announced that he and his wife would match a $1.5m donation from his company’s philanthropic arm. 
 
 In a second tweet, he alleged that Dorsey had failed to contribute to the city’s homeless programs, public hospitals and public schools, despite earning billions and receiving a tax break to relocate in a deprived part of town. 
 
 Dorsey did not respond. He has taken on the housing crisis in different ways, and recently threw his weight behind a controversial bill that would have made it more difficult for cities to say no to development.

 Both billionaires have grown their businesses in the heart of San Francisco, where roughly 7,500 people sleep on the sidewalks each night. The tech boom has contributed to rising housing costs that have exacerbated the problem. 
 
 Tech industry moguls have come under fire in their past for their responses to homelessness, from supporting a controversial proposition, passed in 2016, restricting tents on sidewalks, to public rants. One tech company founder referred to homeless people as “riff-raff” and complained about having to encounter them. 
 
 If voters approve the tax ballot measure, called Proposition C, next month, an estimated $250-$300m in additional revenue would go toward housing the homeless, providing rental assistance and bolstering mental health services and shelters. According to an analysis conducted by the city’s Office of the Controller, about 300 to 400 businesses would be affected. Fifty percent of them would be in the information and financial services sectors. 
 
 A slew of left-leaning organizations and representatives, including the House minority leader, Nancy Pelosi, support the tax, but the newly elected mayor, London Breed, has come out against it, citing concerns that it could put a chill on economic growth. 
 
 “We all recognize the crisis on our streets; we see it every day,” she wrote on Medium. “So I understand why Proposition C sounds appealing, and I know those who support it are well-intentioned. But as Mayor, I must weigh more than popularity and good intentions. I must consider the long-term impacts on our City.” 
 
 Breed has been criticized for her position, especially now that Benioff – whose business will be among those expected to pay the tax – has become so vocal in his support. 
 
 “Homelessness is all of our responsibility which is why we are supporting Prop C,” he stated in a tweet now pinned to the top of his page. “Together, as one San Francisco, we can take on our city’s most complex & difficult problems. As SF’s largest employer we recognize we are part of the solution.” ||||| Add this Tweet to your website by copying the code below. مزید جانیئے

 پیش منظر ||||| On Friday, Twitter CEO Jack Dorsey and Salesforce CEO Marc Benioff publicly sparred over a controversial proposal to fight homelessness in San Francisco. 
 
 When Dorsey voiced his opposition to a bill that would increase taxes on big businesses to raise money for homeless services, Benioff questioned his fellow CEO's personal and financial commitment to the problem while highlighting tax breaks Twitter has previously received. 
 
 Proposition C, which will appear on San Francisco ballots in November, proposes a new tax on the city's largest businesses that could generate up to $300 million annually to aid its homelessness crisis. Benioff has strongly endorsed Prop C, pledging up to $2 million to support the measure, which could cost Salesforce up to $10 million in additional taxes a year. 
 
 Dorsey, however, has sided with the proposition's detractors, including San Francisco Mayor London Breed and state Sen. Scott Wiener, who argue that the proposition lacks the proper accountability and oversight. 
 
 After Dorsey disagreed with Benioff's support of Prop C on Twitter, Benioff fired back by asking Dorsey, who is also CEO of Square, about his and his companies' financial contributions to fighting homelessness. 
 
 For years, Dorsey's companies have benefited from the Central Market Tax Exclusion, commonly called the "Twitter Tax Break," which encourages companies to maintain offices in a rough neighborhood in San Francisco. 
 
 Dorsey responded by telling Benioff that he was "distracting" from his support of Mayor Breed: 
 
 Benioff and Dorsey have a history: The Salesforce CEO tried to buy Twitter in 2016. 
 
 Overall, more than 7,000 people experience homelessness in San Francisco, where detritus indicative of human suffering on the street stands in stark contrast with the city's overall tech-fueled wealth. ||||| Add this Tweet to your website by copying the code below. مزید جانیئے

– Two of the world's top tech CEOs disagree about how to ease homelessness in San Francisco—a city where extreme wealth glitters alongside roughly 7,500 living on the streets, the Guardian reports. At issue is a proposed tax on wealthy city businesses that Salesforce CEO Marc Benioff supports and Twitter CEO Jack Dorsey opposes. "I want to help fix the homeless problem in SF and California," tweeted Dorsey on Friday, but this tax isn't "the best way to do it." Retorts Benioff: "Which homeless programs in our city are you supporting? Can you tell me what Twitter and Square & you are in for & at what financial levels?" Dorsey calls Benioff's questions "distracting," while the Salesforce CEO scolds his fellow exec for fighting "a relatively small tax." Called Proposition C, the ballot measure would tax big-city companies by varying amounts—roughly 0.5% on the gross receipts of businesses making over $50 million a year, per CNN. The goal: Raise up to $300 million annually for shelter beds, mental health treatment, and housing, which would double current city funding. But San Francisco's new mayor, London Breed, also opposes Prop C, citing accountability and oversight issues as well as possible layoffs or companies fleeing the city. Meanwhile,Twitter is among companies benefiting from the so-called "Twitter Tax Break" for having offices in rougher neighborhoods, per CNBC. Now Benioff, Dorsey, and Breed are apparently huddling: "We're all talking now and aligned to fix this issue..." tweeted Dorsey later Friday. "Will keep everyone updated." (This homeless man charging a phone at Dunkin' got a rude surprise.)
