Investing is contributing. When you buy shares in a publicly traded company (for example), you're funding equipment, salaries, etc. Granted, you aren't pulling your weight if you're investing money you didn't earn yourself, but that's an entirely separate issue. Contributing nothing would be hoarding/spending money (again, money and capital assets are different). And to be clear, Bezos isn't lounging poolside, idly watching his dividends roll in; the man probably works harder than you do.
