Thanks for the insight. Cities like San Francisco and New York obviously do have needs for sky-rise buildings, you are right. With the ocean on one side, there is less area to expand into. However, they are also closely connected to other nearby cities. I feel bad for people who work in the cities, and only earn enough to live far away, requiring a long commute.

I personally believe new companies should be expected to develop into outer regions to enhance surrounding communities. Too much density may be good for business growth, but it is not good for people to live this way.

For me, San Francisco would never be the same if they ever remove the "Full House" homes facing the Golden Gate Bridge. These townhouses are so iconic for that city.
