Not particularly. The saying "time is money" applies here: the argument could be made that the "rich people who ride the bus"'s time is worth more, and putting them on a bus where they can do some work instead of driving is a more efficient use of their time. Of course you could argue that the poorer people "forced" to drive their own cars could use that time, but they might not be knowledge workers, which means that time wouldn't be productive to their employers anyways. And this also is entirely dependent on how you perceive value to be created, and the model you choose to use.
