WOTC - Income inequality

I asked this question in the Wisdom of the Crowd:

Why are most governments unable to deal with income inequality?

Here are the responses: (56 Votes)

27 % - They have a vested interest to promote inequality.
25 % - They are funded by corporations and rich individuals
20 % - They have to return to progressive income tax, instead of GST.
16 % - They are fooled by economists who promoted globalization and outsourcing.
13 % - It is a difficult problem.
