evidence: To be sure, Mr. Biden's budget isn't set in stone — instead, it reflects a starting point for negotiations with lawmakers, who ultimately craft and pass spending bills and new tax laws. But the White House's push to raise taxes on the wealthy reflects a push to place a higher burden on the richest Americans in order to increase funding for education, housing and health care, among other priorities. "As Biden has made clear since his 2020 campaign, he wants to raise taxes substantially on high-income households and corporations and provide modest tax cuts to low- and moderate-income households," wrote Tax Policy Center senior fellow Howard Gleckman in a blog post. "And, like it or not, that's what his budget does." [...] The biggest lever hiking taxes on high-income households is tied to the Biden administration's proposal to boost the highest rate on capital gains taxes from 20% to 39.6%, the Tax Policy Center noted.
