You don't have a solution unless you can propose a way this gets legislated and executed. No hand waving. How specifically does this work? Suppose it is day one of my shares being worth more than 100m. What happens?

It's pretty easy.

You can just cap total compensation for executives relative to the lowest paid worker and include equity in that calculation. If you want to pay yourself, 10 million a year in stock, great... You need to pay the lowest paid person 10k in stock or whatever.

Or, you can mandate that after a certain size a worker owned trust/union will own some percentage of the company.

There's dozens of ways you could address this problem. Each have pros/cons. It's not that hard to fix if we actually wanted to fix it though.
