If Trump wins, he plans to free Wall Street from "burdensome regulations"

However miserable government bureaucracy often is - Wall Street and its "short-term profits are the ONE and ONLY GOD" mindset have already proven themselves a complete disaster - for the longer-term prospects both of America, and of the 99.9%. Wall Street needs brutal downsizing if America wants to have a future.

Most do I would think with the exception of some at the top and the libertarian think tanks they fund. I've heard many of those claim that market failures don't exist when it's literally in every Econ 101 book. They make some good points that I agree with, but commonly make bad arguments (e.g. use the argument that it's ridiculous to regulate lemonade stands with health standards, so we shouldn't have health standards for meat packing plants and that sort of thing).

The American political system interprets the will of the people as damage and routes around it.

This is not relevant to a situation in which the details of the fence have been and are argued over all the time. You're implying that whoever is against these regulations must also be ignorant.
