What was the starting point for that increase? 700% of 0 is 0.
If you’ve got a tax-free monopoly on a core infrastructure, an $8B loss is just incompetence.
Then leap ahead to about 2004 where there are something like 210 billion pieces per year with about 750,000 employees.
That turns out to be pretty close to a 700% increase in productivity in terms of workhours per piece, or pieces per workhour.
So, what has been your improvement? (I'm guessing it's NOTHING)
BTW, the Postal Rate Commission approves the postage rates. They are not part of the Postal Service. They denied the necessary increases.
