actually what the postal service could use is a reversal of 2006 congress law that says they have to have 75 years worth of benefits ready. NO other government org has anything like it. NO major private or public sector firm could do it.
without it the postal service would be doing fine.
but the repubs want to take it private so bankrupting it is the best way to get there. directed by bush/cheney the enacted this insane law and for that reason alone they are suffering.
