If I were to guess accounting rules the company uses do not account for that sort of pricing. Lets say I install software X. It lets me take 3 people and put them onto something else. Do I really save '3 peoples worth' of money installing this project? Maybe I now need 2 to run the thing? Oh and you have to get this info out of a manager who probably is not really managing that sort of thing and lets 'the money people handle it'. Also it was explained to me once 'why do we have so many contractors even though they cost wildly more' 'we have two budgets, one I come up with every year and I have to stay inside of that, the other I can change at any time, care to guess which one the contractor budget comes out of?' Software/hw expenditures are not discretionary usually, and usually have some sort of depreciation schedule. A rev sharing scheme would put a damper on that sort of tax games they play. What you are seeing is a side effect of our tax system.
