The post office has been the poster child for DEI hiring for decades. It finally started paying off in the early 2000's. Mail was found dumped in ditches, hidden in employee houses, dumped in the woods because the DEI hires were too lazy to work. Employees were stealing mail, stealing gift cards, cash from bithday and Christmas cards. Employees that could barely read, or had elementary reading levels were delivering mail and packages.
I believe this is why the post office is in such dire straights financially. Badly mismanaged and staffed with people that have low IQ and low skill sets.
Back in the 1950's and into the 1970's the US Post Office was a well-run organization.
The government should hire based on merit and skill, not ethnicity and gender.
