Try telling that to the postmaster Trump assigned. DeJoy made changes to the service looking to increase profits that caused mass chaos to the mail right before the 2020 election (election fraud who?). No idea if all of his changes are implemented practically but I remember much of his shit would fuck a lot of people over, like people out in the country or who get medication by mail. Kudos to the service that somehow, despite having a trump cronie in charge actively trying to screw things, they're still operating really well.
