Im curious in which ways is that a valuable way to look at it, opposed to headcount per road mile, land managed, package delivered, ect? I would expect some reduction in headcount required as we dont need to hand sort every letter, ect.

In a different way of looking at it, federal taxes have outgrown inflation by 10x if you benchmark 1950. In what area are 10X more services provided, and in what areas are 1X services provided.

I've always been perplexed at the assumption that federal spending should track GDP.
