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.

The founders already have the equity, they aren't receiving more on an ongoing basis.
