Think about it people, the USPS already delivers the last mile for packages shipped via UPS (ie shipments from Amazon.com ). UPS won't deliver to every house in America because they don't want to because it would cost to much for them to do so. UPS drivers are also represented by a union, the Teamsters and make as much as USPS letter carriers if not more.USPS should close down and contract with UPS and FedEx. They do a better job, are more efficient and extremely timely with their deliveries. Uncle Sam's mail system is long overdue to be put out to pasture.
The USPS business model should be called "Manage for Failure". Even in times when the postal service is losing money high ranking managers still receive bonuses for making their goals which are nothing but fudged numbers that are manipulated starting with the front line supervisor and up.
USPS management is trying to build the business with new postal products and services ie Flat rate priority boxes, partnering with Hallmark to sell greeting cards with postage on the envelopes etc, but until the do away with bonus base management, things wont change.
