(I'm using the numbers for AT&T) Say you work for a big company so at your salary it translates to 0.0004% ownership. Just as before fiduciary duty and all that the company as a whole has the solemn duty to make it's owners as much money as possible and you make record profits to the tune of $72B. Great job really fantastic. Now instead of a $4B stock buyback it's a dividend paid to the owners (which is you) and you just made a cool $1.6 mil. Sure as hell beats that 2% bonus.
You can't sell ownership as a way of raising money anymore and you have to get loans or issue corporate bonds like all those plebeian small businesses do but the value of your work is returned right back to you as an employee/owner. And you're the board -- let's go (representative) democracy at the workplace! It's gonna make it really hard to push through truly unpopular decisions.
This kind of thing isn't without downsides or a magic solution to all of our problems, but like, employee ownership of business / labor owning the means of production that doesn't require state controlled industry, gulags, or whatever, and roughly lines up with current corporate governance.
