"How to raise awareness? Talk about it. Put it out where people can see. Money is often a taboo topic. My family never talked about money outside the family. We were taught fiscal responsibility, but it was not acceptable to talk about money with other people."

This taboo is not merely a social issue, but is enshrined as policy in the rules of most corporations. One's salary is considered private company data, and one is generally not permitted to discuss it -- even with one's colleagues! -- without violating non-disclosure agreements.

Needless to say, this seriously erodes the ability of the employees to even perceive, much less try to correct, problems with how wealth is distributed.
