Sure. I mean, there's no easy way to compare apples and oranges. Productivity has to be measured in dollars, but making a fridge is not comparable to making a car. It is not comparable to making an iPhone, or to Microsoft selling software or Google selling advertising.
We measure productivity and think that we don't have productivity. It's almost like with your own fitness level or running. You try to improve your own time, as opposed to trying to.... Well, I guess in that case, you do try to beat other people, but I don't know of a way to measure better than with dollars.
