You can defer your income until after retirement. You can move money offshore, you can pay yourself with dividends instead of income. You can start a “farm”. You can do rental property.
Rental property is where I am. Lots of advantages there. Not to mention you have real assets. If you buy bonds or stocks or something... all you have is a promise to payback from the person you loaned all your money to. And, clearly a government that may or may not make them honor their promise.
