Canada

I considered it and did an 8mo internship in Calafornia in 2016. While I would make about 2x what I make here (literally, I made 25CAD/hr in canada and 50CAD/hr in the states doing the same job with the same manager.) I don't think it's worth it for me at least. For one, the medical insurance is kinda insanely expensive, it ate up a huge chunk of the difference in costs while also not being nearly as good and making every trip to the doctors a huge worry and also a cost benefit analysis (and this was with very good, subsidized by my company insurance). I dislocated my shoulder in a biking accident while in Cali, I didn't go to the doctor because I thought it was just a sprain and the doctors would not be able to do anything (while costing me like 200 bucks). When I got back to Canada I got it checked out and they said it was too late to do anything but that it could have benefited from physio when it was fresh.

The healthcare as well as a hundred other factors has knock on effects where poorer folks are very noticeably worse off. Toronto has a lot of homeslessness, but I don't think Ive ever seen a homeless guy using a ruler as a splint on a leg bent the wrong way in Toronto. I don't want to live in a place that does that to people.

Lastly I found public transit to be even more of a joke than it is in Toronto, and as someone that never wants to drive daily that was kinda awful.

While I would probably be marginally more wealthy in the US, I would definitely be less happy, and have a dirtier conscious. I am pretty well off regardless and that was a while ago before the housing crisis in Canada really kicked off so maybe you'll reach a difference conclusion.
