What would fix a lot of this would be a mechanism where the people could vote to remove someone from a federal position

A vote of no confidence and we get to reelect Congress?

Term limits would help too.

Term limits only help when you make politics about the issues rather than who has the most money to get noticed. Make the term limits too short and all you do is give it to the people with the most money considering our politicians currently spend half their time fund raising for their next election.

democratic process has failed us

This isn’t the fault of the democratic process, but allowing money to be speech, companies to be people, and the oligarchy to take over.
