While the USA is a relatively young country, it’s oddly one of the oldest democracies.

I believe most other democracies have better-written laws and better checks and balances because, in part, of mistakes the founders made when writing the US constitution (which was always a highly imperfect compromise, allowed for slavery, and had to be ammended several times just to patch it up).

Hopefully someone more knowledgeable will chime in. But I think the shitshow we call the SCOTUS is somewhat unique.
