That I'm on board with. Demonizing wealthy people for acting in their own best interest within the confines of the law, not so much. I don't hate this hedge fund manager for being a hedge fund manager. I'd be a damn hedge fund manager myself if I could. Even with my meager access to capital, I do invest myself, because I'd be an idiot not to.
I generally don't hate anyone personally for trying make money in a country like the US, the difference in outcomes and quality of life is so dramatic that on a moral level, most things can be justified. So I'm definitely in the hate the game camp, not the player. But I do hate the game, and I think it's important to recognize that it's not something that came about "naturally" and it's important not buy into the idea that any change to the current system is an unfair intervention in the natural order.
I mean, look at hedging. Hedging is important, productive companies use it to protect themselves against external shocks that they can't control or easily predict But we built that system in such way that allowed some actors to come in and make money out of nothing (but again, more accurately, it allowed them to siphon money out of the system without contributing anything to it). We can patch it, we have done it many times, fuck, as recently as 2008 we pretty much banned naked short selling.
Or at the very fucking least, we can stop taxing investment income at a lower rate than labor.
p.s.
One thing I will say to the credit of hedge funds is that most of them are terrible at doing their shitty job. On a macro level, one can argue (and quite a few people did) that hedge funds are scamming money from rich people, and I guess that's not the worst thing in the world.
