Above you recommend we improve something. WHAT, specifically? That is what Don asked. I ask it as well. Very easy to criticize. Terminal Dues being set by others, we did help alter the international agreement at the heart of the issue. As far as domestic improvements, I worked in the USPS for 25 years. I could write for the next 25 years on its problems.
One "really popular" way any company reduces costs is to cut employee costs. And, indeed, they are the largest part of total USPS costs. There are four major unions that USPS must deal with on that issue. And I can tell you that they are slowly losing ground. The USPS is making headway on reducing labor costs. The flip side is obviously worker incomes. So, now solve that problem for us, please Lars. What's the easy answer?
You also do not even begin to know the regulatory relationship between Congress and the USPS. Things like the fact that USPS is mandated by law not to make a profit over a certain accounting period length, so every time it ends up with one, it is confiscated and can not be put back into the system. So, when it fails to have a profit next accounting period, there is no surplus. It must raise rates (or cut costs, which is either reduce service, or cut labor, or both.)
Lars, if "it" was easy, "they" would have solved it all a long time ago. Your criticisms are pretty simplistic. If you disagree, then give me answers, don't just tell me problems.
