Looking at the healthcare and national systems of other countries, I think Korea is a great place for ordinary people to live.

The problem in Seoul is the high housing prices,
but other regions aren't quite at Seoul's level yet.
When you look at the convenience and speed of healthcare, public transportation, and national administrative systems,
Korea is truly top-tier.
If I make a lot of money, instead of immigrating, I'd love to try living abroad for a month or going on train trips.
