Related anecdote, my sister's fiance (at the time) gave me a guitar he supposedly found by a dumpster or in a storage unit. It looked like a Les Paul, but wasn't, I forget the name on the top. I sent it to have it looked over and a couple little things repaired.
The repair guy ended up calling me and making sure I was good with XYZ, and I asked if he could tell me anything about it. Apparently, I had a Japanese counterfeit Les Paul. I guess back in the 70s/80s/90s, Japanese companies would make clones of Les Paul's and sell them for a reduced price, but their quality was kinda comparable to the real deal.
Les Paul would sue and/or send a cease and desist, and the company would shut down and pop up a few months later under a different name, rinse and repeat.
I ended up selling the guitar back in high school, kinda wish I hadn't, but actually ended up buying another a few years later, different color but a Japanese Les Paul.
There are no stocks or profit sharing to make money on via USPS for the board of directors. They receive a salary, and I'm sure they receive bonuses based on performance (not the board level, per se, but postmasters and supervisors can).
USPS is actually a national treasure that we should be very proud of. Representatives of USPS went to Germany several years back to teach them how to efficiently institute 6-day delivery. Our "snail mail" service taught the Germans how to do something more efficiently.
Ass the other commenter said, USPS doesn't receive any taxpayer funding, all of their revenue comes from the sale of postage and their other services like PO boxes and such. They actually used to offer basic banking services too, back in the day, but not anymore.
The retirement funding they referenced was for employees who weren't even hired yet. Thanks to an act passed under Bush Jr, USPS had to pre-fund 75 years worth of pensions, and they were (and are) the only government agency to have that funding requirement levied on them. Simultaneously, USPS cannot change the cost of postage, only Congress can do that, so for almost 2 decades we were forcing USPS to fund 75 years of pensions while not allowing them to set their own postage rates.
If you want to know why USPS is the way it is rather than the Department of Mail like it used to be, I'd start with the Postal Strike of 1970. Thousands of NYC carriers went on strike after being denied a raised while Congress gave themselves one, Nixon called in the national guard to deliver the mail (and they failed spectacularly), and in return for giving up the right to strike, the Dept. Of Mail was reorganized into the USPS. (If I'm remembering all my history right, it's been a few years, I used to be a carrier.)
