Look, let me be perfectly clear. We have to live with the system we have. That system has given us the choice we have. If you refuse the choice, because it isn't the "perfect" choice, you are part of the problem. I'll take a dumpster fire, which Biden is NOT, over a nuclear Meltdown any day of the week and twice on Tuesdays.
Well that is only partially correct: you don't have to live with a bad system, you can always try to improve it or move away into another country. The problem though is gaining enough momentum to reach that goal.
Within the system there's in America this legend floating around about the 4 boxes of liberty: soap, ballot, jury and catridge. The 4th box clearly indicates if something goes too wrong you've got to fight for it by whatever means necessary, even including violence.
There are of course also other ways, like protests, public pressure and so on. But these only will work if the politicians are willing to listen.
And if your system is so degraded that it is only a democracy on paper, but heavily rigged in favor of one party you are screwed, because your vote has no impact at all. America seems to deteriorate into that direction pretty fast with the acting president now having immunity like Louis XIV.
Anyway let's just remember history, namely the GDR in 1989. This was on paper a democracy, in reality a dictatorship because only one party always wielded the power, the SED. People within the GDR were not dumb, they knew about that.
After living 40 years in that construction in 1989 people had enough and wanted real freedom. They stood up, and protested against their rulers openly and peacefully. When the state pushed back, they only came back stronger and even bigger. In the end it lead to the opening of the wall to West Germany, democratization and downfall of the GDR. The whole block of Warsaw pact in fact collapsed, because people had enough.
So - no, you don't have to live with a shitty system which only gives you shitty choices. There are enough examples in history where people overcame such rigged systems. But you cannot do it alone, and it might never work.
In the end the biggest problem and at the same time sometimes advantage of the USA is how inflexible its constitution is. It's almost impossible to reform today or just even add amendments, and has nasty quirks like electoral college (ever thought about how the members of that college are chosen?) which were a necessity in the 18th century but today are just not required any longer due to high speed travel and modern communication.
The problem with the constitution though is now that Trump seems to have cracked the code how to get dictator like powers at some degree legally, which is a really bad thing.
