It's a bit of a shame that the US doesn't really allow part time PhDs (at least not in any of the schools that I asked). If they did, conceivably a lot of these students could get a relatively well-paying job in engineering or a lab or something, and as such the schools could get away with paying less. Part of the reason that I didn't bother trying to pursue the CUNY PhD in mathematics was specifically because the stipend they were offering wouldn't be enough to cover my mortgage (~$2,000/month), and they didn't offer any kind of part-time plan.
