I agree with 100% of the points made in this video. They've correctly identified the problem and their strategy for solving the problem is very sensible.
However, I've been saying pretty much the same thing for at least 25 years and the response from almost everyone I've tried to persuade is this:
1) Good idea.
2) I don't care enough to actually do anything about it.
From about 2003 through 2010, I seriously spent a lot of my time, effort, and also money that I couldn't spare on trying to encourage interest in implementing changes at the state level (mostly Illinois and Wisconsin) along the same lines as this video describes.
Zero interest. It became apparent to me that the public prefers to constantly bitch about a corrupt political system than expend an ounce of energy trying to change it.
