Also, Bernie does not understand economics. It is not necessary to take from the rich to give to the poor.

I believe most Republican capitalists understand this, and Bernie should also considering his econ advisor is one of MMT's most prominent advocates. It is part of the great number of things politicians never say out loud (except Trump on several occasions) but anyone who makes money from their money understands.

Bernie is from the protest generation, as am I, but he never got over his dislike and derision of wealth. He knows that taxes don't fund federal spending, but can't let go of the overwhelming need to punish success. I didn't understand econ until I shed the idea of "punishing" those who succeeded in capitalism and separating them from the opportunistic vultures hiding behind capitalism and "conservative" ideology.
