Milton Friedman once said:

"I have often, when talking to audiences, especially liberal audiences... offered them a challenge. I have said: 'I challenge you to name me a single social measure which has accomplished its intended objectives rather than the opposite, which has not done more harm than good'"

One of the great mistakes is to judge policies and programs by their intentions rather than their results. We all know a famous road that is paved with good intentions. The people who go around talking about their soft heart -- I share their -- I admire them for the softness of their heart, but unfortunately, it very often extends to their head as well, because the fact is that the programs that are labeled as being for the poor, for the needy, almost always have effects exactly the opposite of those which their well-intentioned sponsors intend them to have.
