That's absolutely what I'm advocating for.
Keep capitalism. Allow people to become rich. Use the promise of money to fuel innovation and labor.
... but, after the wealth is generated, we use an extremely aggressive, progressive tax system to functionally call wealth at some level that fuels ambition, but recognized that the majority of that vast wealth was generated by the workers.
For example, Bill Gates at one point was with 80 BILLION dollars. Can anyone say with a straight face that back when he was working out of a garage, he would have been any less motivated if he knew he could get (only?!) 50 million dollars?
Of course not. That's a fortune.. That's all your material needs met for your whole life, and a great inheritance to leave for your family. So why not ramp up all taxes, exponentially, forn income and wealth beyond $50m?
The innovations would be the same, the companies would be the same, but either by taxes or by salaries or stock options, the WORKERS would have shared in that 80 BILLION that Gates hoarded.
