Pretty much any country. If you have $1m in assets you can simply stick it in a passive fund and earn more than the average wage in the highest earning countries. You can certainly live like a king in low cost countries.
If you had said $2 million, I’d say that’s closer to accurate, although there’s still a conversation to be had about risk vs return.
Median wage in the USA is globally very high at just over $60k.
4% is the generally accepted safe withdrawal rate (inflation adjusted) from a portfolio for 30 years holding a mix of bond funds and equities. If you’re trying to live off of it for 50-60 years, 3-3.5% is the recommendation.
