Our Founding Fathers funded the U.S. Postal Service as matter of course -- they realized that open communications among U.S. citizens are vital to our nation's discourse and its defense, too. They treated that funding as merely "the cost of doing business" (I use that term since everyone nowadays insists on viewing everything from the "bottom line").
The Postal Service is supposed to be just that: a service. It was never intended to be a business. It should not be treated as one, any more than the armed forces are. Inability or unwillingness to fund the military is unacceptable. This should apply to the Postal Service, as well.
But even business realizes the necessary value of a "loss leader." Our persistence in requiring the USPS to behave as though it were a private business, according to the unrealistic tenets of the "Postal Accountability and Enhancement Act" (what "enhancement," by the way?) is just one more push in a concerted effort to replace Uncle Sam with Ebenezer Scrooge.
