It’s not even just about choices, it’s about consensus and we’ve forgotten how to see a win from a partial loss. We no longer know compromise at a federal level
I don't think it is so much about win/partial loss but considering large views or long term thinking/strategizing. Especially true in politics because we've developed a system where a representative is only concerned about the timeframe of an election cycle, rather than concerned with what they can do for the people. And we hold them accountable by that metric. So any project that is longer than an election cycle can end up being a game of hot potato where the last one holding it loses. In reality there are several members to blame. It's like how people judge a president based on the economy yet often policies they make don't actually have large effects until years later (definitely some are shorter term, but also remember that effects compound and set a stage). World is too complicated and we're too dumb. We can be not as dumb, but that's not quite easy because complexity is de facto hard.
Not just federal. Federal is where things are most obviously broken, but the same is going on all the way down to the bottom, just slower. I live in a town of ~8k and local politics (over local issues!) is insanely partisan in a way it wasn't even 10 years ago.
And we have forgotten the rational can-do optimistic spirit of problem solving via hard work, (the ideal of) objective thinking, and the hunger for adopting ideas from anywhere.
A lot of this is the result of power centralization in our social and political sphere's. Winner take all dynamics are so immediately and decisively rewarding, that long term, collaborative and independent thinking have become self-defeating (for the political and socially powerful).
Technology can solve many problems. Unfortunately, that can include shifting the price of growing problems into the future and onto the powerless. Enshittification of the whole planet and human condition.
It isn't technology's fault, and if/when society gets shocked into organizing better, we are going to need every technological edge we have accumulated to turn things around.
