I think it just boils down to American voters either having lower standards or not being willing to punish politicians for incompetence.
If the subway service in, say, London or Tokyo or Paris became as bad as some of the systems in the US, it would be a major political scandal and the people running the city would fear for their jobs. That doesn't happen in the US, even in places like New York where a majority of commuters use public transit regularly.
