I only seem to see your average leftist broke loser doing the greed/cheat thing.
It assumes the wealthy don't have a social network and the poor do. WRONG. The wealthy (who have earned their wealth) more often than not, got that way by NETWORKING.
It also assumes (one of the good comments following the article) that wealthy people drive high-end cars and poor people do not. WRONG. Obviously the "researchers" didn't read the excellent The Millionaire Next Door and thereby understand that "old money gets that way by not being spent."
The researchers are trying to make a point in an election year.
