A net worth of $3 million is not "rich" in the U.S. today, especially for someone in his 70's. It is barely enough to retire comfortably, given the possibility that one might end up in a nursing home.
There is nothing wrong with being "greedy." Without greedy people, civilization would be set back 100 years, technology wise.
The implication that "rich people" (however you define it) got there by cheating and stealing is the perspective of someone who has never had a responsible job in the private sector, or run a business. That is to say, it is sophomoric.
It appears that when many people become so wealthy that they simply don't give a shit anymore, they shift to the political Left. People who are still productive (still "hungry") are overwhelmingly on the Right.
This fellow is certainly a "broken record." He hasn't had an original thought since he was mayor of Burlington (or wherever it was). But the fact is that other sophomoric, unproductive, envious people still love to hear his thoughts.
