You are projecting your own envy onto me. You defend these billionaires because you wish to obtain what they have.
All of what you just said is untrue. Billionaires are not responsible nor necessary for anything you just mentioned. Plenty of industries, goods, and innovations happened without billionaires. In fact I'd argue the most important ones in humanity were.
I defend capitalism because it has produced a quality of life head and shoulders above every other economic system, and i know this first hand coming from an ex communist country. I came to this country as a kid with no wealth but became educated and benefited from this great system.
Billionaires are extreme success stories of this system. Bezos created a company that provides over a million jobs to Americans. He provides a service and a comfort to tens of millions of Americans and others, ranging from the poor to the rich.
Spoiled little shits like you grew up in a cloistered system, never knowing what the real world is like. You're weak, so you complain and externalize and blame your failings. Are the billionaires stopping you from getting ahead?
