Andrew Gelman revisits an old hobbyhorse:
Wealthier people tend to be more economically conservative; lower-income people are more likely to support taxes on the rich. This is no surprise: of course it makes sense that if you have more money you’ll have more sympathy with the argument that people should keep what they earn, and if you have less you’ll be more likely to favor redistribution. The correlation between income level and economic ideology is weak (we have graphs in Red State, Blue State making this point), but it’s not zero. Nor would you expect it to be.
