I thought he got $80 mio in Uber shares some years ago. In Ho Chi Minh City - the capital of his home country - you can buy a good freshly cooked lunch like Com Suon Op La (steak with egg, rice and fresh vegetables) for $0.50

So for everyday living, $80mio in Vietnam is going to feel like $8bio in the US (because steak in a restaurant is $50 instead of $0.5 for a 100x multiplier in living costs).

Parent was saying that if you saw this guy on the street, you wouldn't think he's a deca-millionaire just by the looks, which is what you implied. In most pictures he projects a middle manager look.
