What percentage of the revenue derived from an employee's labor would he receive, in an ideal world? The correct answer to this is probably something between 30 and 70 percent, depending on a variety of factors. The
real-world answer to this is "however little we can possibly share, because we want to hoard it all for ourselves", and personally I find that to be a distasteful reality (I find most investors' justifications for their wealth very hollow, they usually all boil back down to "well, I started with more money than them"). Employees have way undersold themselves; I think objectively, most professional employees would probably still be quite profitable to the company if their salaries were quadrupled. And to answer a likely-reflex response to
this, yes, I have run companies with employees before.
Considering that founders are making themselves fabulously wealthy on the backs of their employees, I think we'd all appreciate a little bit more respect than you're showing when you poo-poo employees who want something more closely approximating 1/4 of the share they actually deserve.
