> Don't forget the USPS bans competitors from being cheaper than itself
That’s a disingenuous take. USPS legally cannot be undercut on certain types of postal services but in exchange they must serve EVERY permanent address without price discrimination.
No private company has to do that, nor would any sane profit maximising company want to.
It's also a necessary protection because, for some ass-backward reason, we force the USPS to operate in the black instead of funding it with taxpayer money.
