No late-night buses in Boston

One way in which Dublin trumps Boston is the availability of late-night buses in Dublin, compared to Boston which doesn't have late-night buses (and which is considering cutting back even on evening buses). There are ideas, though, about how to bring late-night buses to Boston.

What seems to work in Dublin is simply making the late-night buses relatively expensive compared to daytime buses. The "Nightlink" (called "Drinklink", or the "Vomit comet") buses are more expensive than normal buses, though still a lot cheaper than a taxi. So why not just raise the fares? That would pay for the buses, surely, and (literally) drive more people to spend money in Boston at night.
