There might be an element of truth to it.
I used to go through a book of 20 stamps every month. Now I rarely mail anything but the occasional greeting card. I stay in contact with friends through email and pay all my bills on line. The only mail I receive is junk mail.
BINGO.
In fact, many people I know are in regular contact over email or on message boards. And now that I have a new car, my car payments will be done using Bank of America's online-based payment service instead of sending payments with a real physical letter once a month.
We ship mountains of Pri-mail and 1st class mail per year. The real problem at the Post Office is that they have 2 to 3 employees doing the same type of job that a single FedEx or UPS worker is doing. I have a hunch the list of disabled people sitting at home on the Gov dime has a much higher ratio than the private sector too.
I deliberately don’t buy stamps. If needed, I go to the PO for just what I need then. One less thing of value to keep around (kids thought they were stickers to play with), and forces me to consider alternate delivery solutions.
My e-mail provider filters OUT my 'E-junkmail'!
Perhaps the PO could learn something here...
