People as a rule (inexplicable, but consistently true) are corrupt, at every level of society.
Poor people, Middle-income people, rich people, super-rich people. No exceptions. Sorry if this offends anyones virgin sensibility--but that is the way it is.
The question is, how does the realization that people are by nature corrupt--relate to union bosses, corporate thugs, and politicians, etc.
Very simply:
Here in the U.S. The people in power make-up the rules--and the rules always lean in the favor of people in power, vis-a-vis corruption.
Here in the U.S., Money = power.
To sum-up...
Corrupt people with money--stack the rules in their favor. Deny it.
Corrupt people without money--get to complain. It does no good.
