I'll chime in on this also. The world has become very polarized and its easy to always bitch. I get frustrated when everybody tries to make a point based on an exception data point, not the norm. Every company has its good stories and bad. For sure the government has more bureaucracy (not necessarily incompetence). So how many oil companies have hidden spills, chemical companies poisoned land and people, internet companies violated privacy, hospitals hidden malpractice, auto companies lie about safety, etc... They just have two different motives. Job guarantees in civil service can cause lack of effort/care, but profit motive can cause major ethical violations and disregard for people (get a machine and we can fire 10%, move it all to asia for 10c per hour child labor, just look the other way and virtue signal). NO organization is perfect, and NO organization is all bad.
I love our USPS and almost all of the employees I have met. Sure, I've also spent hours in line and gotten frustrated at some of the staff. Same for UPS, DHL, Fedex,
Amazon, Card rooms, Auto dealers, the list goes on, etc.... My job has sent me on extended implementations to many countries in the so called 3rd world, including about 6 years spent living expat in 4 different countries. It gives you an interesting perspective and I admire our country more after living overseas. Some of these places have NO mail. You cant even get a postcard reliably. Almost 90% of any packages gets lost/stolen. Despite it's problems today, the US Postal Service has been a wonderful social value for Americans for centuries (yes, not decades). I think the major decline in personal and business correspondence due to email has caused the most disruption as they are now becoming a package delivery service which is a very different business model.
So bitch all you want about delays or loss/theft, but it is a system few others in the world can enjoy and consider how many packages you do get on time, in good condition.
In all fairness, I will also continue to bitch and moan about delayed packages, but I will not throw the baby out with the bathwater for that one package of dozens that came a few days later than expected.
