Are you saiying that waiters do their job for the love of making restaurant goers meals more enjoyable?
And what are you basing your assertations regarding hedge funds on? Other than media spin of course.
Like it or not hedge funds (and investment banks, high street banks, asset based lenders etc for that matter), play a vital role in the economy. Without the investment and lending that they provide businesses would find it very very dificult to expand and invest in growth, let alone start up in the first place, providing jobs, customers for other buinesses, increasing tax revenue and so on.
Yes banking activity contributed to the crash, but the government knew what they were doing and were happy to encorage it whilst it brought in tax revenue (greedy should be taxed at 982374928347%) and consumers (in general) were hapy to borrow way more than they had any prospect of being able to afford to pay back (self certification mortgages).
People need to step back and realisethat blindly scapegoating does not mean that bankers are evil and everyone else is a saint.
