I worked my way through school (as a cook, retail clerk, factory worker, computer support technician, waiter, counselor, corrections officer, and campus police) and earned economics & accounting degrees, plus some "certified nerd" credentials. (I was possibly the only accountant in history who was ever on a CERT/tactical team.) Became a fiscal analyst and college bursar; managed cash, card processing, receivables, and collections. Semi-retired young and became a landlord. Governments are in a race to devalue their currencies. A defense is to own the tangible things that people in any country must have: natural resources & real estate.
