Dear OP.
You might have not realized it yet, but actually the majority of people are just really, really stupid. The US isn't the only country with this problem. The collective stupidity is a really big problem in Europe at the moment *, as well. And that's what's wrong with democracy: even the dumbasses can vote. The other flaw is that parties and those in power will ultimately decide how things get done, not individuals with insight. Yet there isn't a better option unfortunately, because alternatives such as dictatorships are always ruined because of greed, the most basic nature of man. I honestly believe it would otherwise work best.
Really, the best option would be just getting a small plot of land, preferably on an island away from other people, and just live by ourselves, ignoring the outside world. Unfortunately, most people can't afford that. We are fucked. Yet there is hope: the Earth will eventually be consumed by the Heat Death. Better yet, mankind will probably exterminate itself before that even happens. Whether it happens via (nuclear) war, or complete climate destruction. There's already great progress happening in the oceans: I read that as quickly as 2050, there will be as much plastic as there are fish in the waters. We, as a lifeform, will only have to endure just a little longer and then it will all be good.
* Just a few examples from Finland.
- cutting from education funds (and poor people in general) because of current depression. Meanwhile politicians get huge salaries, car benefits (a new car every year), etc.
- a plan where the unemployed get the option to give "a sample" of their know-how to a possible future employer. Length? 6 months. Payrate? 0 EUR. You realize the problems this will cause. The employers will be happy though.
- outrageous taxes on alcohol, plus a government monopoly. People's reaction: day-trips to Estonia, and they come back with huge amounts of beer and spirits. Products that are usually Finnish. So basically: A Finnish brewery exports to Estonia -> A Finn travels to Estonia -> Buys the Finnish beer -> Pays all the taxes to Estonia.
- lots of debt and cuts, yet we get a lot of immigrants from Iraq, Syria, etc. which cost our country even more money annually. It would be fine if they were people that actually were in need of help, yet we constantly get news that the Iraqis in particular volunteer to go back home once they realize what a shithole our country currently is and not at all like the land of fairytales like they were told.
^ All of this because of dumbass voters and greedy politicians. Anyway, this rant has gone off the rails long enough already so I'm just gonna stop here. I guess my point is, just swallow your anger for Hillary, accept that the next US president will be a dumbass too, and try doing your best just managing.
