How are you going to behave once the country realizes all these Populist Trump ideas don't work?

So eventually, may be in a year, maybe two it will be clear all these populist ideas of his (ban immigrants, tarrifs, ban transgenders etc) won't work. Those people with highschool educations are just not all of a sudden get middle class jobs like they did in the 1950s. That's obvious.

What isn't obvious is how you are going to behave (in a few years) towards:
a) The people who put Trump in office but now agree it was all propaganda
b) The people who still believe in Trump's policies even though they failed?
c) The traditional democratic groups that decided to vote for the populist ideas candidate and ignored common sense and history.

As a fiscal conservative (but socially liberal) centralist I can see clearly all these ideas of his aren't going to work. After all if it was as simple as getting rid of the illegal immigrants, adding tarrifs and banning transgenders then all countries in our situation would be doing it.
