Major problems with the US system have been known for a long time. It's been regarded as basically obsolete for over a century now, by the kind of people who study this stuff.
"We basically run a coalition government, without the efficiency of a parliamentary system" - Paul Ryan.
To be more specific, our majority-based government locks us into a two-party system where one party just has to be slightly less bad than the other to win a majority. But our two parties are really just a rough assembly of smaller coalitions that are usually at odds with each other.
The presidential democracies that function usually have some sort of "hybrid" model where the legislature has some sort of oversight on the executive office. But they are still much more prone to deadlock or power struggles.
Germany had 7 major political parties in the run up to 1933. In fact if you look at the history of dictatorships that took over democracies, having 2 to 3 stable institutionalized parties is actually protective. The other thing that appears to be protective is a history of peaceful transitions of power, which the US has the longest or second longest.
Under immense pressure from an impressive list of disasters during the 1920s, it reverted back to authoritarianism in 1933.
I don't think this teaches us much about the US
Nearly every democracy to dictatorship is preceded by disasters.

FPTP, particularly with partisan primaries, has the misfeature that you need to rally the base in order to win the crowded primary field. This leaves only extremist candidates heading toward the general election. In a country like the U.S. where voting is not compulsory, this turns off the moderate electorate, who are forced to choose between two extreme candidates that both seem batshit crazy, and encourages them to stay home.
What is the money doing that the voter can't overcome?
Nonetheless, an individual citizen still has to support some political cause (even if you are completely politically disinterested, there are multiple factions claiming that your inaction is tantamount to support for their opponents). Whatever information about the world you think is true, or whatever political cause you think is in your interests, someone else can point to a monied interest who supports similar things. There's no way to use the absence of big money as a heuristic for what political causes are good or bad for you to support.
There's a set of similar questions one could ask about exactly how you implement a ban on "voting yourself other people's stuff", in an adversarial political system where everyone has a different idea of what that means and is motivated to use whatever constitutional framework exists to ensure that their idea gets structurally advantaged.
Voting yourself other people's stuff would be that the safety net is bare minimum to keep people who are going through unexpected issues alive. But no one gets to live in the social safety net. No one who is receiving these kinds of benefits from the government should expect name brand anything, or to even be able to choose what food to eat, or to travel, or even pick who you socialize with. If you want to eat steak, you have to be a net producer. If you want name brand clothing, be a net producer. If you want to go to the beach, be a net producer.
Everyone who should pay some amount of tax, and anytime there is an increase in government spending, that amount that they are taxed should go up. If there is a decrease in government spending, it can go down. But everyone pays something. People need to have skin in the game. The US's current situation where nearly half the country are not net tax payers is not sustainable. Anything that can't go on forever, won't. So the country should ease into better situation, where the country is a nation of producers and not a nation of consumers, instead of hitting a brick wall where suddenly your ration of beans just stop.
Having a failure of parental upbringing and education system causing someone to be incarcerated seems cruel. Should a child who ran away from home & school to avoid family abuse be incarcerated? There are so many current systems of society (education, police, disability, etc) that have failures at the margin that adding incarceration seems over the top.
Yes, we should implement this as it’s never been tried before! Oh, wait…

Perhaps instead of reading’, writing, and ‘rithmetic, maybe we should test one’s knowledge of history, eh?

The US is mostly hurting itself here, our portion of emissions is mostly historical now, and if we have more expensive and less reliably energy because we are dumping money into decrepit coal generators rather than cheaper renewables, that will only limit the US's economic growth even more, and make the US a smaller chunk of emissions overall.
I have a very rosy view of the future of energy for the world, especially for Africa which can be completely revolutionized with solar and batteries. But for the US, it's dark days. We need to stop hitting ourselves, but as long as hitting ourselves and hurting our economy is owning the libs, part of our body politic is going to keep on doing it.
Is the US hurting it's future economic potential and infrastructure stock out of ideology? Absolutely. Do I care if the US continues to fight against these energy technology torrent rapids out of ideology? I do not. That is the US' choice to impair their future infrastructure and capabilities as a nation state. I can only observe and comment on a suboptimal system I do not control.
I still feel an obligation to fix the mess here, as much as possible, and will continue to do so, but full minimization of US-exposure has never sounded so good.
