Are you implying “nice” US suburbs don’t have drug disorders?

This makes me think you haven't spent time in any of these cities.

99% of Vancouver by area does not have anything resembling 'SF level drug disorder', and if your 'nice US suburb' didn't just punt all of its fucking problems into its nearest downtown, it too would have an East Hastings, or three.

It probably has a lower homicide rate (and a vastly lower vehicular homicide rate) per capita than your 'nice US suburb'.

That same 'nice US suburb' is also, for some reason, packed to the gills with terrified people who have an inexplicable desire to own guns for 'self-defense'. Self-defense from what..?

Having been to quite a number of what I would call 'nice US suburbs', and knowing people from them, a significant fraction of them act like they are living in some lawless Mad Max hellscape. How do you square this circle?
