The United States Postal Service is in jeopardy due to legislation passed by congress requiring it to fund its pension obligations 75 years into the future. The USPS is entirely self funded and doesn't cost tax payers one cent.
To help fill the coffers of the USPS, Congress should pass a law requiring any entity doing business with the United States Government to use the USPS as its exclusive postal courier instead of FedEx, UPS or other private courier.
