“The 28,000 rural post offices that are no longer needed are manned primarily by WHITE WOMEN.”
Small offices in my area have been cut back, and they are on the frontier of the Newark Food Desert (suburban bordering on urban). A healthy mix of “preferred minorities” (including white women); any white guy I’ve seen is over 50 (hired when they were allowed to hire white guys).
There are exceptions ~ it is a large organization. But those post offices have just about the same number of employees as postmasters or substitutes or clerks as USPS has black employees.
This has been a classic problem politically speaking ~ for a very long time. The postmistresses have more Senators in their balliwicks than the black fellows do, and that cuts across the partisan landscape.
