Every Year, the shipping companies announce rate changes. Fedex and UPS typically have a 5% increase. Well a year or 2 ago, USPS announced instead of a rate increase, they were going to cut rates on some parcel services making them competitive with Fedex and UPS.
Well Fedex and UPS blew a gasket, and went bitching and moaning to Politicians about it. So in response, under political pressure, the USPS raised their parcel rates.
So instead of USPS shipping a higher volume of products direct, profitably, their trucks are now full of money losing "last mile" parcels that they deliver for UPS, Fedex, and Amazon
