Maybe the problem is with how vague I am being. Of course there is tremendous value to the creative labor you have performed in developing your techniques, creating your designs, etc.
But the monetary value of your hypothetical employees’ contribution is “all of that additional revenue” because, without them, you cannot access that additional revenue.
Employees don’t accept a fraction of the monetary value of their labor because it’s fun to get paid a fraction of the revenue they generate; they do it for some other reason.
