A leading physicist claims to have figured out why the U.S. Postal Service loses a lot of mail and delivers most of the rest late — post offices are “architectural anomalies” that cause time warps, wreaking havoc with letters, packages, sorting machines . . . and sometimes even mail carriers themselves.

While the Post Office is indeed stuck in some ancient pre-industrial era, a more likely explanation for why I had to wait in line for an hour to send a package this Tuesday is that incompetent government bureaucrats don’t have to care about the service they provide because of a coercive government monopoly that prevents infinitely more efficient private carriers from competing with them.
