A lot of folks online are worried that one casualty of The Pandemic could be the U.S. post office. Everyone's preoccupied with masks and gloves and hand sanitizer and TOILET PAPER and getting their groceries and with the prospect of vote-by-mail looming, this might be a good time for those who have always hated the institution to do it in or seize control of it or something.
It is true that by some measures the U.S. Postal Service loses money but that's only by some measures…and that's with the folks in Congress who want to see it eliminated or privatized doing everything they can to make it lose money. I think that given what it costs to mail a letter, the U.S.P.S. does an extraordinary job. People who are not computer-savvy (there are plenty of such people) rely on it to communicate, pay their bills, etc.
Want to do something to keep it around? Buy a lot of stamps. You'll use them eventually and they won't be any cheaper in the future.
