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.
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.
Imagine you lived in a feudal kingdom. Would you just shrug at all the wealth of kings and lords made off your back? Most people did, but thank god times have changed for the better. Perhaps we can change them to be better still.
