These people are racist assholes and their plans are as dumb as they are.
Only if you assume the plan is meant to benefit the country. If you assume that they want to profit from the suffering it makes more sense. Irrational, cult-like mindsets are easier to peddle when people are miserable.
I think they are definitely malicious, but I don’t think they are capable of such cunning planning. They yearn for the Germany of the 50s and 60s and that means, among other things, no EU.
I don’t think they yearn for any time that actually existed in the past. They yearn for a simpler world, one where people all have the same skin colour, sexual orientation, religion, life goals,… and where good things happen to people like them and bad things happen to people who are different.
