What is your point?A raise in rates does not translate to no subsidies.
The USPS funds all normal operations from postage sales. Congress only pays for those services that it requires the USPS make available at before market rates. This includes free postage for the blind, free voting materials for overseas voters, and only charging domestic rates for service between the United States and the Freely Associated States (i.e., Republic of the Marshall Islands, Federated States of Micronesia, and Republic of Palau).
There is an additional appropriation that is supposed to cover the debt service left over from the period when the USPS was turned into a quasi-private entity but was not allowed to set rates high enough to cover its operating costs.
Are you aware that in the years that the Make America Great Again people think were so great, the USPS was a fully governmental organization with all rates heavily subsidized by Congress as a necessary public good?
