Capitalism has changed the power of the world economy, capitalists can now easily dominate and control a country's economy, they are the real rulers, unfortunately many countries do not care about issues like this so they choose to close their eyes and allow capitalist practices.
I think that viewpoint is a bit too narrow. A capitalist can be some who makes a 1000 per week, which is in many countries a low income. Same with calling people rich because there is a belief that instead of a thousand he makes 10k without any proof that it is that way.
Even a millionaire is not that rich as many think just because he has 2 houses each 500 k worth.
