Honestly, at least some of these issues can be addressed game theoretically... But having a well educated populace is key to most of those strategies.

If people can't (or won't) critically evaluate claims, and vote, then how can we expect the system to work in their favor?

Take Trump as an example of that latter point: I had friends who believed that because he was a businessman he would be able to run the country better than Hillary. They assumed this was true, and even when presented with his poor performance in that role they didn't yield. I didn't even receive a counter-argument. The conversation ended.

As a side note: we already raise billions of dollars every year in the form of taxes.
