The fact you melded the two different functions and organizations together suggests you are just spouting and have nothing behind it.
The postal CEO is called the Postmaster General. He has no authority whatsoever over the Postal Rate Commission.
Exactly why they are failing. Exactly why they should be privatized.
Distinction without difference.
Whatever the organization of the USPS governing body, upshot is that those with the power to set prices refuse to do so in a manner consistent with cost realities and profit goals. Any business operating in that manner would have those decision makers ejected by stockholders in short order.
“Have nothing behind it”? Come on! Imagine a grocery store which had two separate boards: one controlled operations, the other pricing, and neither had authority over the other. How long would the store last if the pricing board refused to set to _at_least_ break-even levels? It would be bankrupt in short order! Ditto here: the Postmaster General may run operations, and the Postal Rate Commission sets pricing, and so long as the latter refuses to raise prices to what the former can bring expenses down to match, the USPS is on a fast track to bankruptcy. It’s ridiculous, and you’re defending it!
