I certainly brain-drained myself out of the US because moving to Canada was far far easier than trying to move myself to the US. I could afford to start the process, sure - and hire a lawyer to make things go smoothly... but instead I spent a total of about $500 and just self-filed some paperwork and I'm now a Canadian citizen. And, at the end of the day, I'm much happier with my current citizenship because the far reduced healthcare risk exposure and egalitarian working conditions are just much nicer to live in - there's still a significant wealth gap but wealth at least isn't glorified up here.
