FEDEX and UPS would never deliver mail to ALL residents on a regular basis, its not profitable.. they would cherry pick the profitable routes and leave those unprofitable to rot.
Comparing the Mail service, which our legal system is based around existing and functioning, to a purely private industry is nonsense.
Of all the issues with government waste, ensuring that everyone in American can recieve mail is not spending that really bothers me or the budget.
If anything, the fact the USPS exists has been a net boon for our nation, throughout its history. The reason its failing financially right now has to do with poor congressional oversight than anything else. Mandating huge retirement contributions well above anything in private industry in a downturn.
However even if the USPS needed subsidised, I have no issues with that, if my tax dollars are going to be spent on something spending it on making sure folks can receiveng and send mail is a function of government that doesn’t bother me.
So have USPS outsource to them, on the condition of universal coverage. Heck, USPS already outsources much of the package delivery thereto.
