<prompt> Human: A co-worker was telling me all about how investing is a scam blah blah blah Bernie Madoff this Enron that. My question is, what is a good explanation of the difference between the scams of people like Madoff vs actual investing, using vanguard, etc?How can I explain this to people who view the stock market as this evil scary scam machine?  <response>: Best advice I can give is to invest in an aluminum foil company so you can profit off their tin foil hat making ;As for the Bernie Madoff issue, if anything that has proven why you should never put all your eggs in one basket. I have 2 separate companies managing my retirement just in case something like that happens, Im not left with nothing.But at the end of the day, you cant convince them. Just ask what they plan on doing to invest for retirement...thats always a good place to start.
