The way things are going with Bitcoin banks, Bitcoin gambling etc will Bitcoin actually solve the evils associated with money?

In the UK we blame the bankers for all the problems. What makes the Bitcoin Banks/Exchanges different than the greedy bankers? You say 'it's decentralized' but the people who have all the Bitcoins actually control the whole economy... like Goldman Sucks control the world.

Just a few thoughts, don't troll me too hard.
