The USPS stuff was historically corporate welfare that let UPS and Fedex have a third party handle unprofitable delivery.
USPS is beefing up its parcel operations and is getting more competitive. Generally speaking, in my city the post office performs better for most ground scenarios, mostly because they are separating parcel delivery from the standard routes.
That is the exact opposite experience in my part of the world. The local post offices have become fiefdoms.
I could not find any accountability without having to go through Amazon. And the USPS claims poverty with what's left of their 5 billion dollars surplus still sitting in their pension fund.
