Elon Musk, Bill Gates, and all the other brilliant entrepreneurs that propel our society into the future are most often not motivated by money.
Elon clearly doesn't give a shit about his money. He only wants to own and control his companies. His wealth is simply a byproduct of that.
Capping billionaire wealth won't stop innovation.
If you just let them control their companies, then they probably will work just as hard if you take away their money over a billion dollars.
It will help to stop the growing inequality that will continue to destroy our society.
The government is controlled by the wealthy elite, so I don't get your point. Their job should be just to redistribute wealth with (ideally) an universal basic income.
But, the elites don't want that because it's too simple. Basic income redistribution scares the hell out of them and they will destroy the country rather than give up their beach house.
While I respect Paul Graham's career and his abilities as an entrepreneur (I mean we are doing this on Hacker News), I am always very skeptical of wealthy people talking about "How to get wealthy".
And his essay isn't bad, but it's still coming from a place of insane success, much of it not duplicatable for 99% of the people even in such a opportunistic place like Silicon Valley (I know he addresses this randomness of success in his essay).
The wealthy elite will ruin this country. Look at our president. The asshole is walking example of shitty capitalism at it's worst. He is literally the leader of our country.
