Probably. But you choosing to have your kids go to a suburban school doesn't singlehandedly cause it, and you choosing to remain in an urban environment won't singlehandedly fix it.

So the choice remains, do you want your kids to go to a good school or a cruddy school? If you care about your kids and are mildly practical, this question answers itself.

i lived in chicago for 20 years. the city schools were funded just fine, the teachers' pensions (generous to say the least) weren't. i'm a lot more interested in my kid being safe and challenged at school than i am in paying for some retired teacher to take more vacations.
