That video above could be said about New York in 1977 or 2007.
It's hard to describe, but there is something about living around people like
@Sparda29 and
@ChalupaBatman86. It's not just for the culture, it's for the encounters. There's a microsociety that can be had for everyone, and those two cities, the opportunity is limitless, with the downsides being what you see. If you're a person that's not prone to living in a city, where any place is like every place (try most suburbs in the US), then that appeal never works. NYC and LA QoL comes from being the premier cities rather than material cost of living, and you do pay through the nose for it. But NYC in particular is like no where else in the world, not even the US.
