Put the United states Postal service up for bids becaus we cannot keep up with the loss and inefficiency

There is a need to make the US Postal service pay for itself or make a proit. This service is old tech. expensive to maintain and UPS or Fed X can do a better job. The Postal Service continues to loose Billions of dollars how long would a private business last? The way this US gov. funded service is poorly run and cannot even make a decision to cut out Saturday delivery. I believe as many that we should sell off the assets and shut it down so the service can be run like a real business.
