Philly cost of living is fantastic. The local job opportunities don't pay as well as DC or Boston or NYC or SF. But you can just work remotely for a big company and get a reasonable wage. Not being a parent I don't know about the school system.
I would not call it fantastic. It's better than the cities you just named, but at least average, probably a bit above average.
The Philadelphia school district is garbage. The other kids will be less affluent than you for the most part. Anyone who cares about their kid's future moves to a suburban school district asap. It's seriously a networking thing because socially life long friends get minted in elementary and middle school.
Yep. I was responding to the person's comment about cost of living.
Yup not arguing just adding my perspective. There are some gems though like science leadership academy which is a charter magnet school. If you're stuck in Philly it's probably the best school. I personally know someone that used to work there doing IT and teaching kids programming.
