The Wiemar republic had 40% democratic socialist before market forces brought about a right wing response to an economic condition.

We have no left wing parties. The Democrats and media have kneecapped the threat of any alternative but a right wing populist response to the coming economic crises.

We are not immune any more than Germany was in the 30's. I see 'Never Trumpers' moving into the democratic party while it sheds what it had of a left.

There are no leftists political alternative capable of taking advantage of the situation ripe for left wing solutions. I'd really like to be wrong here but I don't think so.
