Usually yes, but the executive branch has currently gone rogue, i.e. been firing investigators, stealing 500B of taxpayers money without any oversight etc. This level of corruption is unprecedented for the US and it is clear that the foundational system of checks and balances does not work anymore.

No but it well might be a slow descent into a Russian-style "democracy" instead.

Literally, (LITERALLY), one of our political parties is spending its energy at the moment denying that the final three problems exist, and blaming the controversies about them on the first, explaining how it's all the fault of the other party.
I mean, we actually do have politicians in this country who want to see solutions to that stuff. You should consider voting for them instead of tut-tutting them for not being centrist enough.
At least one reason might be because democrats aren't actually as extreme as you feel like you're Supposed To Think. You might consider voting for some if you look at their positions instead of jumping in to complain about their "extreme perspectives".
When the Cold War ended, we (the US) lost our Worthy Rival (in the sense discussed in the book The Infinite Game). During the Cold War, both political parties agreed to get along because of an external rival. We now have several Worthy Rivals but fail to realize that, so as a country we have nothing to rally around except for an inaccurate belief in American Exceptualism.
I am hopeful that all of the problems (political, COVID 19, economy, and racism) that we face might unite the country.
As for Facebook acting in our public interest: I will believe it if it ever actually happens.
