There's likely nothing he can do as a single investor. It's like the Prisoner's Dilemma. He could opt out, but now he has to find a new line of work, and meanwhile there's plenty of other investors who will take his place and nothing will change. There's no way to get them all to change their ways at once.
The only solution is government action; it's one of the big reasons we have a government, to fix things that "the invisible hand" cannot or will not. The problem is that our politicians are either totally corrupt or inept. So just like they failed to prevent the 2000s mortgage bubble, and the 1990s dot-com bubble, and the 80s S&L crisis, etc., they're going to fail here too.
In short, if you want to blame someone, the only people to blame are the voters.
