I think one way of looking at this is that all of your examples are negotiations. (Between buyer and seller, tenant and landlord, employer and worker). So of course, anything that makes the deal much sweeter for one of those two parties ends up split between them. Roughly if the negotiating strength of the two parties is such that your boss get 50% of the value, and you get 50%, then if something adds extra value to the equation (a more productive tool), you only see half of it. If your negotiating position was only getting you 10% then you will see very little indeed, even from large improvements.
I suppose the silver lining is that if something adds value for the other party you will benefit. You might not even know what it is.
