Under actual "darwinistic capitalism" anybody who wanted to would be able to start a competing transit service, even if it stole all the customers of a current one. At a minimum, you'd see a thriving private jitney industry - private bus services outcompeting the public ones and private part-time cabs underpricing the metered ones. No, to get mass transit this bad requires active interference with the workings of "darwinistic capitalism". In particular, laws making it illegal to compete with the established quasi-monopoly firms. The government at various levels doesn't just do a bad job of providing transit, they also make it illegal to compete with the crappy transit they provide. Fix either half of that equation and things are a lot better.
