There’s no moral reason to have that much money. If you earned $2500 a day (about a million dollars a year) it would take you just under 1200 years to earn a billion dollars. I personally believe you should earn more if you work harder than others but there’s simply no way anyone could work hard enough to deserve more than anyone should make in 15 lifetimes. If you are lucky enough to get that amount of money there’s no moral reason to keep it all.
Now think about how Bezos is worth 192.4 billion dollars. Hopefully that helps folks understand the problem. And by problem, I mean the largest threat we are facing to human existence. Every other issue we’re having stems from the fact that billionaires exist.
