You realize NYC isn't just high-rise apartments, right? There are plenty of single family neighborhoods. Yeah, definitely cost more to live there but wages are typically higher as well. I have multiple friends with kids that live in the city (one in an apartment, one in a single family home) and they both love it. The opportunities they have at their fingertips is far greater than other areas. When I visited a few years ago, I was also surprised by the amount of parks/green space actually available.
I've personally lived in the US midwest, US south, and a short stint in Japan. Each had aspects that were great but each had drawbacks. In the midwest as an example, cost of living definitely lower than many places but job opportunities and overall amenities were typically hours away by car. Cost of living is lower because the winter sucks. Nov-Feb, no desire to go outside in the gray gloom.
So basically, why judge how others want to live their life?
