Here is a great blog post explaining the Postal Service "crisis," a subject that is near and dear to my heart.
The Postal Service is a public service for We, the People, not a business. The Service is hamstrung by people who pretend it is supposed to compete and then won't let it. They won't help with taxpayer dollars and say it has to compete in the marketplace (again: the Department of Defense is not required to break even.) Then they give it rules that no private company could survive. Then when it gets into trouble, say that government doesn't work, start laying people off, selling off the public assets, and saying it has to be "privatized" (so all the gains will go to a few already-wealthy people instead of to the public).
