My apologies if I misunderstood, but your use of the term "extraction" implied (to me at least) that money accruing to shareholders was being taken out of value produced solely by employees. I agree that the key is the proportion. One way to think about this is to imagine if one of the employees in question quit and started operating independently. How much $ could they make? If it's more than they made while working for the company then the proportion taken by shareholders might indeed be too high. But if it is not more, then you've got a hard hill to climb when making your argument that the proportion is significantly off.
