The Democrats don't have a better solution and they're not good at pretending to listen and pretending to have a solution. The Republicans don't have a solution, but they're masters at pretending they care and that they have an answer. Trump is going to wave his hands and make human labor more efficient than robots. He'll stop all of the cheap imports competing with US products and still keep prices at Wal Mart low. Sure, if they can just build that wall, the manufacturing and mining jobs in places where there are no Mexicans will come back. The robots will be put out to pasture and we'll start relying on human labor in manufacturing again.
Well, he's 100% in charge now, so it will be interesting to see what happens. I wouldn't bet against the fundamental rules of economics, though. Those have a pretty solid winning record, especially when you compare it to the record of politicians promising jobs.
