Let me bring your attention to following verbiage from the Postal Reorganization Act:
(a) The United States Postal Service shall be operated as a basic and fundamental service provided to the people by the Government of the United States, authorized by the Constitution, created by Act of Congress and supported by the People. The Postal Service shall have its basic function the obligation to provide postal services to bind the Nation together through the personal, educational, literary, and business correspondence of the people.
(d) Postal rates shall be established to apportion the costs of all postal operations to all users of the mail on a fair and equitable basis
The combination of both of these parts to the Section 101 of the explanatory intentions of the Act, that the USPS operational budget shall come from postage fees alone and that it is obligated to "provide personal, educational, literary, and business correspondence of the people", we could solve the issue of Net Neutrality and spark a new economic revolution akin to the Industrial Revolution. I would propose to take the billions of that which has been sequestered to fund the ridiculous 75 year pension to be freed up and allowed to build the infrastructure needed for the USPS to begin offering internet service wirelessly as a Wireless Internet Service Provider (WISP). Having the USPS operating as a WISP would be aligned with the intentions of the 1970 Postal Reorganization Act, as the correspondence is the intended purpose of the USPS and though contemporaneously was exclusive to the physical paper-centric correspondence, the USPS is not shackled to that limited definition of communication which is the bedrock of an informed electorate within a democracy. What I am envisioning is a municipal wifi except on a national level, that unlike the municipal wifi projects would be paid for by the end users instead of through ad revenue and local government taxes.
While providing competition to traditional internet service providers (ISP) that are currently biting at the bit to impose slow lanes to their customers, having the USPS entering the market would create a floor as far as maintaining net neutrality and allowing their users to freely browse the web without being slowed down when interacting with private ISPs non-preferential content (think of Comcast slowing their customers' traffic whenever they browsed other than subsidiary NBC/Universal content on the web). With the pseudo government agency, the USPS, operating the WISP the private providers would still retain the market differentiator of having their users' privacy as a priority possibly baking into their service end-to-end encryption and faster speeds of hard lines and fiber to the curb than the USPS' WISP. The freeform nature of the Internet would be retained with a critical mass of consumers guaranteed access to all of the internet, and have the positive effect of either forcing the hand of the for-profit ISPS to continue net-neutrality policy or possibly that the slow-lanes be so cheap that people would possibly patronize both services.
