You've described the justice systems of modern progressive countries and what would you know, they work fine. The US needs a firm hand because it's culturally savage. Folks think about themselves and corporate "culture" is enshrined as something good and expected. Everyone sees the exploitation of other human beings and denigration everywhere, is it any surprise that they cannot behave in a manner that has a little compassion for themselves and everyone else? The entire environment is fundamentally dehumanising. No amount of localised niceness is going to undo decades of absolutely brutal culture.
