Capitalism, Socialism etc. are just words, the real problem is the distribution of wealth, no matter the system you always have people who take advantage of the system, create laws that are only good for them they become the elites, the untouchables, that is why we have so many billionaires popping up in all places regardless of what political system they have. And this comes down to greed, you know if you have $100 million you don't really need 200 but you want it, and are ready to do anything for it, like the Simpsons Mr. Burns said: I'd trade it all for a little more. I am not against someone getting rich, it is how they get rich that is the problem.
And by doing anything I mean they are willing to maintain an army and police just to make sure the people don't get too uppity, I know, I am living through it right now.
And you know another thing, if all of a sudden all the people who believe in equality were to receive an inheritance that made them very rich their points of view would suddenly change.
