Maybe giving everybody the right to vote was a mistake. Certainly people are saying that Trump should have never been elected President for the past 4 years, so I'm not alone in this, right?
A government always represents who gives it power, and hands the benefits of society primarily to those who give it power. If people are not represented, they will be cut out, their situation will get worse, and it will probably end in riots (like, a whole lot more than now) and even rebellion. That, really, is the essence of democracy. There will inevitably be hell to pay if the people are unhappy, so a system that is designed to inherently pay more attention to the people should be less likely to implode.
I think democracy needs to be looked after and carefully tended. I don't think politicians and other elites have looked after it, and the attitudes that led to Trump are the result. Trump was the result of a failure of the political classes and socioeconomic elites. It only remains to be seen whether the Trump experience motivates them to do something about it. The problem is that Trump made insanity the party line and they let him do it. Can they reclaim their party from him?
I fear not, because outside the president, the US system lacks leaders. Leadership devolves to people like McConnell and Pelosi, who are fixers, really. They don't have a vision, they don't want to improve things, they just play the system to benefit themselves and their parties in a very narrow way. They must be pushed into changing things or replaced, and I don't know who will do that.
