...as there are some suburbs where you can live reasonably.
True, though "affordable" is often relative around here.
A lot also depends on (a) where your job is, (b) how viable public transportation is for you to get to that job, and (c) how long of a commute you're willing to accept.
If you work downtown, public transit's a great option for commuting, and you can live in the city (because you probably don't need a car). If your job is in Schaumberg or Naperville, you're likely looking at having to drive to work, regardless of where you live.
I know folks who have nice, good-sized houses, that they didn't pay a fortune for...but they live in Kane County (about 45 miles west of downtown) or Will County (about 50 miles southwest of downtown). They're willing to put up with an hour+ train ride each way to work, in order to get that.
Ultimately, someday, my lovely bride and I are going to get sick of how crazy it is here, I'll change careers, and we'll move to Wisconsin. But, not in the foreseeable future.
