I wasn't born in the US. I've lived in other countries. There are other disadvantages to places like Europe or Australia (or Japan or China, where I've also spent time) that make the tradeoff not worth it to me. The biggest issue is that you'll always be a foreigner. Even if you jump through the hoops to become a citizen, you won't be accepted the same way that Americans accept immigrants. US conservatives are painted as disliking immigrants, but that's only true for immigrants who don't culturally assimilate. Conservatives have no problem electing immigrants like Winsome Sears, Arnold Schwarzenegger, and Young Kim. The mayor of Helena, Montana is a refugee from Liberia. The state with the most foreign-born governors is Georgia. Anyone who claimed that these people aren't "real Americans" would be shunned and shamed across the political spectrum.

There's also the issue of employment and compensation. My skills are worth far less in other countries. I make over $250k/year in compensation, and my taxes are low enough that I've managed to accumulate "fuck you" money before the age of 40. I could retire, but I want to maximize my family's quality of life. It'd also be nice to have an aircraft and a cabin on some land in the middle of nowhere. My chances of accomplishing those goals in another country are much lower. (I'll probably have the cabin in a few years. The aircraft... well, we'll see.)

If I wanted to move to an area with low crime, I could choose from plenty of places in the US. I don't live in those places because, similar to other countries, I'd have to take a massive pay cut. As remote work becomes more commonplace, that could change.
