In Blasio's warped Communist vision, driving out the 1% is a good thing. He hates them anyway, even though he is one of them. He claims to represent "the working people", but he has crushed them ten times more than he has hurt his declared enemy, i.e., wealthy people.
Like most Communists, he is a delusional, irrational, fool. He would tear down all of America if he could. New York City is just his starting point.
