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.)
