@JBKOEven though I've lived near NYC for lots of years and I think I've been in all the cities in the top 10 in population, but even NYC crowds most often don't compare to the crowds I've been in when I've been some places in Europe or in Russia. I've never been to China or anywhere on the African continent, so I can't compare them.
I like living near a big population center but I'm not so sure I'd want to live right in its midst.
I grew up in a small town (under 5000 with nothing much bigger close) and I've chosen not to return to that kind of area because I do like the amenties more prevalent in bigger population areas and am willing to live with the inconveniences of the extra people and traffic. I don't consider that being spoiled though - it's what I'm interested in at this stage of my life.
It's been nearly 50 years since my ex and I drove cross-country several times, but in those years what did surprise me was that even close to the big cities we toured, we could drive just a few miles out and be in the country. That hasn't been true in the NYC area for decades - and I've also seen lots of growth happening close to other Eastern big cities so I assume the same thing is happening in the rest of the country.
