The post office does a lot more than just deliver letters... and so do the route carriers. Think about the elderly and shut-ins who don't have computers and their only connection to the outside world is their mailman - who also, btw, is usually the first one to notice when something is wrong by the sight of uncollected mail. I see so many stories of elderly people who would have died all alone in their homes had it not been for awareness of their mailman who called for help. Most of these people also rely on the mailman to bring them their SS checks and their meds. You say, "$0.55 coast-to-coast and 3+ days to make it happen." like it's a bad thing. How old are you? If you think that's bad, how about having to go to the LIBRARY, search through a wooden file cabinet card catalog for a BOOK, then have to go locate it on a SHELF in a huge BUILDING... like looking for a buried treasure! Ahhh, the good ol days.
