I think liberals are more often control freaks. I read another thread today that detailed a thread over at DU where the participants were dreaming of a good old fashioned command economy. And it occured to me that this sort of stuff is most appealing to somebody with an education, a good pedigree, or some reason to not fear that they would be fed into a state controlled industrial machine and spat out the other side to wait in a bread line.
People are more likely to support such a thing when they can see themsleves as masters of such a world.
You are 100% right. I see them all the time. They are called "Humanities professors."
