@Andrew M. NYC has many of the same problems. It's nice to be in the 'in' place, but as you grow in maturity and investing, other areas start calling.
When you are doing a fully cost-oriented analysis of the area to live in, it's important to think of where you might (have to or want to) let yourself slide in another area. Here is a good example:
I can complain about the cost of living in NYC. However, I own 0 cars, no pets, and live in a fairly small apartment. If I was to relocate to Georgia, we would certainly be in for 1 car, maybe 2. We would likely have more housing time and utility costs (landscaping work, air-conditioning). Furthermore, I would be taking a wage hit. This is specific to me because I still work a full-time, non-real-estate job. Given all that, the move does not save me as much as I would like. In the short term, it may cost more.
I find this index to be helpful in this case:

For the record, I do plan to leave NYC. Ultimately, it is too expensive, crazy, and over-regulated. But in the pre-children stage of life, it makes some sense to stick around.
