Far left populism is not really a good thing, but it is very important that the fat rich constantly live in fear of the guillotine. There needs to be an equilibrium. In the last few decades, the rich have lived carefree, comfortable lives; they need to FEAR again. That impulse will help fix things.
Fear is more likely to lead to repression than to concessions.
I think 2016 proved that national polls were trash a lot more than 2012 proved exit polls were trash...
The national polls were actually pretty good in 2016. There was a large last-minute shift to Trump, and the late national polls showed about a 2-4 point lead for Clinton, which is exactly where it ended up.
