In theory, San Francisco. However it is literally inaccessible to anyone except the top .01% and anyone lucky enough to be a homeowner there before prop 13. Every city in the US that is even close to being worth a damn is like this and every day I pray to the great train in the sky that the Bay Area becomes Hong Kong 2.
San Francisco? Los Angeles, Chicago, Dallas, Atlanta, Miami, Philadelphia and Boston would all like a word. Los Angeles and Chicago in particular.
Population-wise some of those are too low compared to Chinese T1 cities. But there’s no official definition so…
Yeah I wouldn’t expect any of those except maybe LA to be considered tier 1, I said those ones because they’re all larger than San Francisco lol
