Right on! This is what I have argued a long time. In my view the problem is Americans like to think they are the best country in the world and treat the founding fathers as infallible Gods.
What I noticed most when living in America is how rich it is and how well developed the private sector is while the state itself functions in a manner that reminds me more of the 1800s than a modern state.
Since it’s founding there has been surprising little update and reform of how the USA operates.
And in particular you don’t see the US copy any best practices from elsewhere. How American elections work today has a lot in common with how they worked in Europe in the 1800s.
America has a weakness in its bureaucracy. Instead of primarily being professional, too many important positions are elected and thus subject to partisanship.
The normal model is you got elected officials at the top setting the political direction. People further down should not be political but in the US system far too many yes-men can be hand picked by political leadership or elected directly by voters.
And perhaps the most important institution in a democracy, the free press, is utterly broken in the US. On he one hand you got outlets like FOX which serves as a mouth piece for right wing populism. On the other side you got channels like CNN which is primarily sensationalist. Looking for whatever sells and gets viewers. Serious news is which could create well informed voters is neglected.
