That's a nice theory but I don't want to bet future of mankind on some feel-good logic. In my view, a-holes remain a-holes, self-centered narcissists double so.

Feel like trump for example got wiser and saner and more rational the second term? Because literally whole world believes otherwise. He has his whole clan to think of due to consequences of his actions, if he cared. puttin' is same, just sour keg of bad beer that should be poured down the river (or some better ecological disposal of garbage).

Why do you think 70-80 year old "middle aged" politicians would get a chance when 150 year old "boomers" with wealth and powerful networks might be able to call the the shots?
