There is no need to bring history into this discussion since we've never been in this situation before (global fiat monetary system with multinational corporations operating on a global scale with regulations which create monopolistic, anti-competitive dynamics).

It's a logical certainty that if Tesla (or any company) sticks around for a few hundred years, the later generations to join the company are going to get a bad deal compared to the earlier ones. If you really want to look at history; just ask any new Apple employee who joined during the past 10 years what percentage of Apple stocks they own... Compare that to what early employees who where there at the beginning received for the same type and quantity of work.

If any big corporation is propped up by monetary policy such that it is never allowed fail no matter what, it will create an anti-competitive moat around it and that corporation is guaranteed to turn into an unjust pyramid scheme.

The only thing we can do to fix the problem of injustice and inequality is to remove the artificial conditions which prevent the formation of free markets.
