I do wonder what's keeping people there long term.
With that amount of money you can have an amazing life in so many places on this earth, and these people definitely have the resources to do that. Have these people never experienced life abroad? Quality of life is much higher elsewhere.
Crazy to me that some people in the comments believe that 80k$ dollar is peanuts. Even in Germany I could easily live with that for more than 5 years.
If I had that kind of money lying around I would move to another country, pay for my whole education, learn a new language and still have enough money for multiple full-time start-up attempts.
