Also, because the majority of humans on this planet don't have any power to actually do anything. A few rich people in power control our lives. Thinking otherwise is just deluding oneself. There's no way around it until we rebel on a planetary scale (even if it means just not going to work for a few weeks, the rich need to be forced to feel discomfort), we just don't like thinking about this reality because it makes one realize one is helpless.

Bonus points: With countries like America eroding our education system at every turn, our citizens will soon be too dumb in one or two generations for the independent thought necessary to even know how screwed we are.
