America used to have a draft, where half our population  served and met others who thought  differently. I think America forged some decent people in such a way. 
I would love to see a massive change in our electoral system, starting with allowing third parties to run and form coalitions as is done in the  parliamentary system. It is too much to expect that modern Americans will just revert to some sensible, decent two party representation that allows for intelligent discussion and un-thwarted voting. But if we had five or ten major parties, maybe the sheer numbers of voters would restore decency.
Of course, we would also need to find a way to make running for office easier, and not the insane marathon of mud slinging that goes on today. Some countries have very short election seasons, and they restrict the ads that are heaved about.

But change in America is something that tends to happen in times of disaster. Maybe a President Trump would be that disaster.
