The beginning of the end was the fax.... The USPS didn't evolve and still relied on the good "old fashioned" handwritten letter to a huge extent. The day of the hand written letter is gone and with online bill pay and draft...... well the heartbeat was getting weaker. Email struck a HUGE blow with the volume of letters taken away from the profit line and now with smartphones and texting the USPS has basically become a dinosaur. With the exception of possibly the cockroach you must evolve or die....
