Long story short, the 30 year review and analysis states that rich people (those that pay their senators/congresscritters) get their laws passed, even when rejected by the bulk of the common person. And yet popular nonrich-popular laws are regularly dismissed without a consideration.
1$ = 1 vote. It happens at the regulatory level, the bill level, and the vote level. That's corruption no matter how you frame it.
