Sure, if employees owned more than 50% of the company then they'd have more "seats at the table". In my experience the employee poll is negligible though from a "power" point of view.

My point I guess is that there's no materially different upside to owning shares where you work, or just shares outside. And shares outside diversify your income stream.

If there is a material difference in terms of power, well then I guess that's different.
