I would say you are incorrectly using the word value. Both parties are getting the best deal out of the transaction they can. Just because the things I work on may make my company more dollars than my salary a year doesn't mean the "value" is different - it's much more complex.

Here's an example: one aspect of the "value" my company provides me is risk-subsidization. If I was freelance, I would have to work on constantly finding clients. The grass is always greener...

Edit: it also REALLY depends on how you run your business. This gets into more philosophical stuff around greed and leadership (ie: how much you take, how much you share with your company etc). Providing jobs can be anything from charitable to borderline slavery.
