You can live like the upper class in Thailand with just 1 billion won

In Korea, you need about 5 billion won to be treated as upper class,
but in Thailand, it's possible with just 1 billion won.
However, it might be a bit tricky if you don't have additional cash flow.
If you receive a pension of more than 1 million won after retirement,
you can fully enjoy an upper-class lifestyle in Thailand.
Though it might be a bit difficult in Bangkok, where many wealthy people live.
If you live in a moderately sized small city, you are truly upper class.
The local residents will look up to you.
