> Congress cut its taxpayer funding, and directed it to run itself like a business, not like a public service.

Not really. Congress forced the PO to run itself like no other business or government entity with the goal of ruining it. The 109th Congress wanted to promote the belief government can't do anything efficiently. It was called the Postal Accountability and Enhancement Act and intentionally places huge burdens on the USPS which no other business has. Without those, estimates show the PO would still be hurting, but no where near its current state. So Bush can say "Mission Accomplished" about one thing and be right about it.
