On one hand, government postage services should be seen as a service rather than a for profit organization especially when they’re on the hook to deliver to places nobody else will.
On the other hand, it’s past time to recognize that the timely delivery of a handwritten note from one person to the next within the week is not part of the requirement of the service anymore arguably since the advent of the telephone and certainly today in the world of email, messaging, and voip.
The service should be preserved but perhaps the daily door to door service could be cut. I say this as someone who insists on paper bills.
