The American constitution is riddled with problems that many later democracies managed to fix. In general, the founding fathers envisioned a system where amendments were far more common and they didn't realize they made the bar too high. And that doesn't even touch on the electoral college, first-past-the-post voting, vague descriptions of the role of the supreme court, and no method for no confidence votes. Of course, it would be next to impossible to fix these in America because it would require a significant rewrite of the constitution.

The only way this will change is if the rest of the world leaves America behind and the quality of life here becomes so bad that radical change becomes possible.

But you are right that Trump won the popular vote in 2024, so you can't blame that on the system. But a functioning democracy would have more constraints on him. Our legislative branch has been dead in the water for 20 years at this point.
