Earlier quoted context omitted.
Maybe, I mostly gave that disclaimer to say that it actually doesn't matter much. Even if it's worse, that's still better, because it's over there. But yes, generally, I assume virtually every developed country (and some of the kind of developed countries) have a more just and competent legal system than the US. The US is an interesting beast, because when you compare it to the entire world on a bunch of stuff, it do…
Not being an expert in every single country's legal system, I would guess that the USA's is about middle of the spectrum in terms of badness/fairness/justice.
These things are hard to weigh objectively. For instance, in America the police don't take bribes, you can't bribe your way out of a traffic ticket. The cops will laugh at your attempt and pile on more charges. But if you're a local business owner, the bribes to local politicians are far from unheard of and all manner of corrupt dealings between business and local government is prevalent. So how you rank America's corruption depends on how you weigh those two forms of corruption. There's not one single objectively correct way to do that.
