I find it hard to believe that most of the rest of the world has, but it seems some countries have. Many countries don't really have functioning mail delivery, whether public or private. The CATO Institute says "The U.S. ranks near the bottom of the Consumer Postal Council’s 26‐ country 'Index of Postal Freedom.'"[1], but they only looked at 26 countries, and even then, I'm not sure what that index looks at. I found a report from 2012 but it's long and I'm not gonna dig into it now. Do you have examples of which countries have and what led to the change?
