When one thinks about the history of the USPS, one has to admire the role it played to bringing civilization to the frontier of the 1800's. Countless settlers depended upon the USPS to connect them with civilization back East. Mail order houses like Montgomery Wards and Sears and Roebuck sent much needed goods to customers via the USPS. It was possible to mail your kids to relatives through an oversight in the postal service regulations. To this day, live chicks are delivered to rural customers by the USPS.
It is unfortunate that our politicians didn't fully understand the significance of the of the postal system to the well being to the country, both past and present, when it chose to privatize it.
