Because those people mostly don't exist and you're not given the choice. RenTech exists but has to cap the size of their internal market-beatung fund, because their strategies only scale to a certain extent. They're a hedge fund, not a financial advisor - and they do indeed do what the GP said and just invest for themselves. Almost all other folks out there revert to the mean after a while. But that doesn't mean there aren't good financial advisors. They're not helping you best the market, they're helping you ensure a good financial future within the scope of your existing wealth and income. They do apply their skills to themselves, but you need a job and a big base of money before s&p returns will make you rich. :)
