Congress messed up the post office

No, Amazon is not the problem as idiot Dump has ranted. Congress is the one that intentionally and deliberately sabotaged it in order to privatize mail services.

"The Postal Accountability and Enhancement Act of 2006 (PAEA), which some have taken to calling "the most insane law" ever passed by Congress. The law requires the Postal Service, which receives no taxpayer subsidies, to prefund its retirees' health benefits for 75 years into the future -- this covers the health cost of employees not yet hired, and in many cases not even born yet. If that doesn't meet the definition of insanity, I don't know what does. This is a $5 billion per year cost; it is a requirement that no other entity, private or public, has to make. Without this obligation, the Post Office actually turns a profit. Some have called this a "manufactured crisis." It's also significant that lots of companies benefit from the burden that make the USPS less competitive; these same companies might also would benefit from full USPS privatization, a goal that has been pushed by several conservative think tanks for years."
