If all the companies that are willing to hire you equally treat you like crap, you aren't really given much choice. In terms of entrepreneurship, it carries a ton of risk. People living paycheck-to-paycheck typically aren't able to carry such a risk with no safety net (family, etc.).

Price is set by supply and demand, not by either seller or buyer.

In a market with multiple suppliers and buyers, the price will sort itself out.

That you don't like that price has nothing to do with either side being "evil".
