Being able to trust in the stability of banks is subsidizing the economy, not just wealthy individuals. It isn't CEOs who got tossed out of work in 2008, it was't wealthy individuals who had a 27% unemployment rate.
Wealthy individuals constantly try to game the system. Not letting the games they play hurt the rest of us is an entirely proper role for the government to take on.
I think the problem is when those games don't hurt the individuals playing them. After 2008, most of those banking executives who screwed things up saw few consequences.
I agree that it's a good move for the government to use taxpayer money to prevent an economic collapse. But that's still the lesser of two evils: the government should be working harder to disincentivize the kind of behaviors that make wealthy individuals think that playing these sorts of games is worth the risk.
I'm not sure what "working harder" should entail (I'm no expert on this sort of thing; others are), but I think it's pretty clear they're falling short.
