WHY DO YOU THINK RICH PEOPLE STAY RICH?

They don't. Not historically.

Over 100 years ago, Ford, Carnegie and Rockerfella were much wealthiest than Bezos and Gates today.

Those who stay wealthy tend to:

1. By being frugal relative to their income
2. By having well-diversified investments
3. Not relying on one income source
4. Not giving all their money to charity upon death!
5. Teach their kids how to compound the money and not be like these rich kids.

You can’t be high-wealth sustainably without spending less than you make.

Now sure, being frugal isn’t the same for everybody. If you are earning $100M a year, and you spend $50M, and invest $50m, you are still being frugal relative to your income.

That is no problem, provided you can reduce your spending dramatically if the money dries up.

Now look at Warren Buffett. He `only` had $1M at age 32. Much less than Mike Tyson and various (now broke) celebrities. He didn't make his first billion until his mid 50s.

Now he has 60billion plus. Now how does he live. He often eats $2-$3 meals and still lives in a relatively modest house. 

Most people who stay wealthy long-term are frugal relative to their worth, and could become very frugal if they ever got into financial problems.
