This Explains a lot.

“Intellectuals [Democrats (ed)] cannot operate at room temperature.” There always has to be a crisis–some terrible reason why their superior wisdom and virtue must be imposed on the unthinking masses. It doesn’t matter what the crisis is. A hundred years ago it was eugenics. At the time of the first Earth Day a generation ago, the big scare was global cooling, a big ice age. They go from one to the other. It meets their psychological needs and gives them a reason for exercising their power. Many intellectuals’ preoccupation with the poor is very much the same thing. The thing that gives it all away is that after they say, “We must have this program because the poor can’t afford medicine, or can’t afford housing,” they will splutter if you say, “OK, let’s have a means test so it really goes to the poor.” If they were really concerned primarily about the poor, they would agree to it. But they are bitterly opposed to that, because the poor are a lever to reach other, political, goals.”
