Very interesting if truth be known Liberals HATE the middle class, for the same reason Karl Marx hated them. The bourgeoisie (middle class) tend to be independent, self-reliant and difficult to rule.
Socialist governments throughout history destroy the middle class FIRST. Stalin slaughtered the Kulaks because they opposed collectivation. Castro chased the middle class from Cuba after stealing their property same for Venezuela! Middle class GONE! Why are USA (misnamed) progressives any different? In fact the only middle class in any Socialist government are the low-level government bureaucrats, teachers and police who enforce the rationing, tyranny and poverty on the rest of us.
