From the perspective of a employee and/or human, that does seem like the most fair way of distributing what the company earns, sans the money that gets reinvested straight back into the business itself. But I'd guess that'd be more of a co-operative, and less like the typical for-profit company most companies are today.
Hipothetical two people cooperative that produces simple hammers. One specializes on wooden part, the other on metal part. How much each of them earned to the company? (Or producing and selling; or one spending his lifesavings to buy pricey hammer-making-equipment while other presses buttons on said equipment)
Suppose as well there are a thousand people lined up to make the wooden part but hardly any for the metal, then surely the ones who work on the metal part will (try to) command a higher wage too.
The problem with calculating based on value provided not market rate is value provided easily sums to more than one unless you consider replacement cost.
What you're describing, that money would go to whoever brings in revenue directly, is the myopic viewpoint of Sales with an emphasis on closing deals with nothing else. If it wasn't for the rest of the work, there'd be nothing to sell!
