The Postal Service receives no tax money.
It's financial struggles are because of a Congressional mandate that they prefund 75 years worth of retirement benefits in a 10 year period. Fedex or UPS doing that? Will they delivery a letter anywhere in the US for 45 cents?
Without the mandate, the USPS is in the black. It's a system that works but is being cannibalized in order to make the payments. There is still a need for postal service in spite of email. Even the big shippers often use it for final delivery.
We are in trouble if it disappears.
That's my understanding of the issue as well. I don't think all the USPS bashing is deserved. It's my understanding that our super smart, totally selfless, give the shirt off their backs Congress has a lot to do with the woes the USPS is facing.
