People often pull out the supposed quote from Churchill that "democracy is the worst system, except all the others". But, they omit an important bit from the actual quote:

Many forms of Government have been tried, and will be tried in this world of sin and woe. No one pretends that democracy is perfect or all-wise. Indeed it has been said that democracy is the worst form of Government except for all those other forms that have been tried from time to time.…

IMO, a critical part of that quote is "that have been tried". The US is especially dumb here. A bunch of 25-year-old aristocrats from 250 years ago tried to design a government system. They did a pretty good job. But, they weren't political geniuses, or if they were, they were heavily biased by the times they lived in. They came along nearly 200 years before the development of game theory, let alone centuries of work in political science. The constitution should be a living document, learning from the mistakes those 25 year olds made.

They didn't understand the degree to which parties would take over. They didn't know about game theory showing that a FPTP system inevitably devolves into a 2-party system. They thought about the threat of a demagogue in the president's chair, but they were blind to the idea that he'd be the head of a party, and his party would prevent impeachment.

Unless it's too late, the US should start amending the constitution and fixing these bugs. But, instead it's seen as a holy document that should no longer be changed.

The last few centuries have been a process of taking power away from a hereditary class and distributing it to the people. But, the name "aristocrat" actually suggests why that form of government was supposed to be good. "Aristos" -> the best. "Kratos" -> rule. Aristocracy was supposed to be the "best" people ruling the country. It was the people who were educated from birth about how to govern ruling over peasants who had no education or knowledge of the world. Of course, the fact it was hereditary meant that the kratos were no longer really aristos.

But, maybe, there's a germ of an idea there. For example, it makes no sense that education policy be decided by a cabinet member / minister who is elected by being the least bad option in some random district, then joining the inner circle of the leader, then being appointed in charge of education. The people making decisions on educational policy should be educators: teachers, professors, scientists who study learning, etc. Of course, you need checks and balances, and maybe popular voting should be part of that, but not in the current way. Maybe professional organizations and unions should have a formal role in government, instead of simply having to spend money to lobby the education minister.

I don't know the solution either. But, what I know is that we should still be searching. Maybe the US is too far gone, but other countries should be coming up with new tweaks to their systems. Maybe (hopefully) that will mean less direct voting, and more decisions made by subject-matter experts.
