Which city has the most rich people?

Wow, I always wondered which city has the most rich people, you know? Turns out it's New York City! I saw this article in Forbes – they’re usually pretty reliable – and it said NYC just dominates when it comes to millionaires and billionaires. Makes sense, right? Wall Street and all that. Hong Kong and Moscow are apparently up there too, which I guess isn't that surprising. Oh, and Mumbai! That one kind of surprised me, to be honest. I mean, I knew India's economy was booming, but… wow. It really makes you think about where the money is in the world, doesn't it? It’s like, these cities are all major financial hubs… kind of like how my friend Sarah moved to London after she got that crazy banking job – she said the energy there is electric, just buzzing with deals and opportunities. I remember her saying something about how London used to be higher on the list but has dropped a bit recently. Anyway, these rankings really show you how global finance is concentrated in a few key places, huh?
