The IMF can only "force" countries to do things if those countries want to lend money from them. And even then, a country can lie with impunity in a round - unless it wants repeating lending rounds, and lies in important and bad ways.

Also, I've never hear about the IMF forcing a country to dismantle its public-education programs. When Brazil was on their hook they did anything but that, and in the later years IMF helped improving it.
