Don't come to Canada unless you like woke/left-wing extremists in every corner trying to boss your thinking, way of doing business, and continuously trying to f**k you with new taxes, tax hikes, "environment fees" while you have to wait 25 hours minimum at the ER to see a doc because the healthcare system is third world level. I don't get foreigner's fascination with Canada, i see a lot of expats wanting to move there for some odd reason thinking it's f*****g paradise when it's virtually impossible to get rich here unless you're 1) A criminal, 2) A politician, 3) The son of someone rich who made his wealth elsewhere.
UK is fine but avoid London unless you want to get stabbed for your watch or something in broad day light with cops doing nothing about it.
Dubai is fine if you don't f**k with US laws, never seen a rich guy get cockblocked there unless he brought the trouble with him from what ever corrupt shithole he came from. But its a superficial city with expensive entertainment and the people that go with it so make sure you're comfortable with that vibe.
Switzerland is great, but insanely expensive. The thing with the swiss is that they're not really racist (Unless you go to remote cantons with hardcore nationalists), they're just insufferable cunts by nature (Especially the ones in Zurich) so you may vibe with them or literally hate them. Not everyone likes living in a country like this despite all the advantages. Like others said however if you're rich you're basically untouchable.
Australia is a shithole, avoid it. Good nature, landscapes, beaches, climate, but how they turned into a dystopian dump during the pandemic shows you how paradise can quickly become hell. People are NPCs like in Canada so they'll cheer for any crazy orwellian policies the government can come up with, that includes raising your taxes and f*****g you over your business if a financial crisis hits.
The U.S. is a sinking ship so avoid it. Even Miami became a dumpster once you get out of the tech bro rich areas. Florida was a good place until influencers made every pleb from california/washington state move there, and all the hood rats from upper east coast suddenly wanted to "start over" in Miami. So as a result you got a lot of crime, fraud, etc and real estate is overpriced.
