This is easily one of my favorite Thatcher moments, and it is every bit as important now as it was then. It is the fundamental problem with the leftist complaint about income inequality: if they truly are worried about income inequality, then they are not worried about the actual welfare of real people. They are just mad that some people have more than others. If they take this seriously, it means that fixing poverty is no less an acceptable policy goal as making everyone poor. After all, if the gap is what is important, it shouldn't matter how much anyone has so long as nobody has more than anybody else.
This goes right back to George Will's point on the difference between the right and the left; the right wants equality of opportunity, the left wants equality of outcome. The whole Occupy movement, in fact, smacks of an irritating "it's not fairism." It's not fair that there are winners and losers, so let's make everyone a loser. This doesn't apply just to the left's views on wealth inequality. Check this beauty from Ezra Klein:
Markets and outcomes be darned. It's not fair!
