Wealth is not the same thing as money. Wealth is as old as human history. Far older, in fact; ants have wealth. Money is a comparatively recent invention.
Wealth is the fundamental thing. Wealth is stuff we want: food, clothes, houses, cars, gadgets, travel to interesting places, and so on. You can have wealth without having money. If you had a magic machine that could on command make you a car or cook you dinner or do your laundry, or do anything else you wanted, you wouldn’t need money. Whereas if you were in the middle of Antarctica, where there is nothing to buy, it wouldn’t matter how much money you had.
It’s easy to confuse having money with being wealthy. If you have a ton of money, but no close friends, and are in terrible physical health, that’s not wealthy. True wealth is not just having success, but health, happiness and all the intangible things you can’t assign a monetary value to.
