The real answer is that the US doesn't want public transit. I visited a rustbelt town several years ago, and a new mall had been sited specifically so that it would not be on the bus network: being accessible to the people who ride the bus was considered a liability for the businesses that would rent space in the mall.

More recently I visited a much nicer midwestern town which is planning an expansion of its bus network amd optimizing traffic lights for better bus flow. There is a new mall on the bus line. The difference is that 95% of bus riders in this second town are upper middle class college students.
