This is not a problem with public transport but with utter lack of urban planning and convoluted social dynamics in the USA.
Dense cities and lack of urban sprawl reults in awesome places to live and you don't need to even use public transport in those as everything is just close by.
Also - IMHO the problem with the USA is more focus on competition (you have to "win") instead of cooperation hence more fracutred society that yields more povery and "not-nice" public spaces...
> The worst argument anybody can make is "but that's just life in the big city!" If so, then I'm not going to live and raise my family in the big city. Airy-fairy principles of efficiency or an arguable notion of convenience will not take precedence over safety and quality.
I live in a rather smallish city/town (~45k).
