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.
This probably explains the flight of the middle class from blue states.
California, especially LA and the Bay Area, is the leading example of this phenomenon.
