"USPS being in big financial trouble" should be considered a crazy idea. To me, it's like saying the "Senate" is in big financial trouble or the Federal Reserve is in big financial trouble. USPS should be a federal entity. They should be managed just like the State department.
What the USPS accomplishes is amazing. For a few dollars, you can send anyone a letter or a package to anywhere in the United States. The amount of productivity and the improved standard of living they provide incredible.
I always find that argument hilarious because the USPS was required to actually have conservative, healthy funding for their pensions - something no other state or federal agency does! And this is supposedly a bad thing! Just look at Chicago for an example of unfunded pension liabilities - a ticking time bomb.
