Look at the subtext and it's all about who has the money and who doesn't have the money and how the moneyed people are getting it and what they're doing with it. Furthermore, I always see a lot of carping on LJ and other places, most of it quite legitimate in context, about being poor.
Hence, a poll:
Which gets people more het up, really?
Race, ethnicity, or religious differences---intolerance, prejudice, general lack of understanding
Economic differences: poor vs. rich, attitudes about money, differences in handling money, differences in priorities
