This isn't really accurate. USPS had a break even (not profitability) legal mandate since 1970-2006. They would adjust prices each year to hit break even. And that's what happened - they roughly broke even each year.
After a 2006 with broad bipartisan support, the UPS was able to make a profit (not just break even) but a price cap was added (to be reviewed every 10 years). They couldn't raise costs beyond inflation. A stamp to send to anywhere in the USA - anywhere (Alaska, Guam, etc.) - currently costs 82 cent. The postal union is against this, usps management is against this, and business mailers are for it. Dont you love all the ads USPS delivers you?
They have not been break even since 2007. They currently lose about $9B/year with $2.7BM being controllable and the rest largely being pensions, retiree health plans, and workers comp charges. Their core business (mail) has been declining for 20 years and no end is in sight. In 2020 they loosened the cap a bit (allowing USPS to raise prices). Business mailers tried to sue them but lost.
So this attitude that they should just lose a bunch of money and be backstopped by the taxpayer, when mail is less critical than ever, is an recent idea and is aligned with business mailer lobbying interests. It seems obvious to me that they should just go back to the break even mandate.
I was confused by this until I realized you are missing some logical steps in your (accurate) argument.
The 2006 law took away the safety net (ie the ability to charge whatever is needed to break even).
The “you can now make a profit” rule actually made it HARDER since it came with a price cap.
It told the USPS: You can keep any profits you make, but you cannot raise prices above the rate of inflation to get them.
This forced the USPS to absorb rising costs through internal efficiency rather than passing the bill to mailers
By no means was I implying that the ability to profit means they did profit. Im just stating what the law was.
True, but isn't this because everyone knows that USPS is a dying business already?
Not when combined with the idea that spam mail senders should be legislated out of legality.
