Robot Wisdom delivers a timely link to this summary of what's wrong with the IMF as world government. The harsh part is the extent to which you and I are complicit in massive injustices. I feel like the "debt relief" bandwagon is probably the right one to push.
And if you doubt that this is really the way the IMF works, look at what they're requiring of Argentina and Turkey, and the debacle of privatization in countless other countries who have been forced to sell off their only assets to Western corporations. Bolivia's water system is probably a good example.
