Why pay $80,000 per year in an expensive country for mediocre care when I could spend $10,000 for my parents in our cheaper home country for exceptional care. There's like almost 200 countries in the world and life can be very very nice in honestly most of them with a bit of money.

Edit: this is a very useful strategy for dual citizens or people with family in more than one country and ultimately taking money earned in a wealthier country and bringing it to the economy of a poorer country is a benefit to the poorer country. I'm not saying this is a solution for everyone, but it is a very valid situation for some people. One could retire early or enjoy a much higher standard of living and care by just leaving a higher COL location. The same can be done within a country such as leaving the city and moving to a rural area where the COL is much lower.
