You just described a big part of why people do not like free markets. Corporations are allowed to accumulate an enormous amount of power and then use that power to abuse whoever they want (aside from a sliver of circumstances covered as protected classes). I think want most people want is a reasonable middle ground, not unchecked corporate power.
