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.

Executives do get equity as part of their compensation and it’s a huge reason for the massive disparity in wealth.

This is well studied stuff.

Since you aren't willing to engage in a discussion in good faith, implying whatever I have to say about your 5th-grader-level economic plan to just seize all the shares is bs, I recommend you ask chatgpt why it doesn't work.
