Let's see, that's:
* 207 employees per county (650,000 / 3141) Link.
* 13,000 employees per state (650,000 / 50)
* .0018 employee per US person (650,000 / 350,000,000)
What was the number of employees in 2000? Should be a bunch less than 650,000 given email and online everything. But I bet it's not, primarily because the employees are unionized.
Let's at least end Sat delivery and cut an appropriate number of employees.
Number of USPS employees:
1960 = 408,987
1970 = 548,572
1980 = 536,373
1990 = 760,668
2000 = 787,538
2010 = 583,908
2014 = 488,300
2019 = 496,934
