Yes, I agree that they're taking the SV approach of "move fast and break things". They believe that government is severely broken, and this is their chance to reform it in significant ways. But obviously that's little comfort to you, if you get caught up in any breakage.

What I wish is that the Democrats had heard the plea of so many working class Americans, who were basically saying the same thing as you. "Your policies, (like mass immigration), make me fearful for the future, and I don't know how I will survive, or thrive". It was the dismissal of their fears, often with derision and insults, that pushed so many of them into the arms of Trump.
