JK Rowling is far more like Elon Musk.

There are some countries that do somewhat better than the US (though it's pretty much an inherent issue when you give people power over others), but there are more countries that are about as bad or worse. Most countries are neither in the US nor in Europe and less developed countries are generally not doing better than the US on the human rights front (at least before the current presidency).

I'd say outside the US there is generally less of that macho psuedo military 'alpha male' vibe and it is generally less tribal with internal protection, but there will always inherently be something problematic with a job that places people above their peers in power and the people that apply for it. Whilst many may do it entirely for good reasons there will always be bad actors. I dont really see ACAB as entirely true, even in america, but i think the role itself as a job will always be a problem in society.

Why shouldn't it?
