News sources are a poor substitute for the truth these days as they only talk about the sensational headlines, NOT the underlying FACTS of the matter. I know a lot of people that work at the USPS and have family working there.
Try looking up how much the USPS overpaid into the health care pre-funding (estimates range from $30 BILLION to over $75 BILLION, not 6.9 Billion). Try looking up how many years the USPS earned Billions in profit and the treasury department raided those profits so they could pay down the deficit with it (thus all profits earned magically disappear and cannot be used to pad the expenses in the following year). Try looking up what the profit margins would be if the Bush administration law known as the Postal Accountability and Enhancement Act of 2006 (which was passed by a Republican Congress and signed by a Republican president) requiring the USPS (no other government agency has this requirement) to fully pre-fund their health care for future retirees in advance. These aren't routinely figured into the numbers posted by most news articles these days.
The USPS would have been in the black the past three years in the middle of a recession and the loss of a lot of 1st class mail to e-mail, etc. Look at how postal rate increases MUST be approved by a committee outside the USPS. They cannot make quick changes to market changes like gas prices like UPS and Federal Express can. Now look at the profits of UPS and Federal Express the past couple of years and how much they've hiked prices. Now compare their prices to the USPS.
You've done NONE of that and yet you talk like you know all about the USPS. You don't seem to know a thing. Or perhaps you do and are purposely distorting the truth? Your article from the United Liberty web site isn't even news. It's a Republican tirade to privatize government (in this case the Post Office, which would get the favorable parts cut up and the rest dumped, leaving America without reliable mail delivery to every address).
FYI, the push to end Saturday delivery is the first step the Republicans want to make the Post Office fail against its competition so that it can be piece-meal cut up to make more profit for America's greedy (that's what the Republicans do to everything they get their hands on). It's why health care costs are so darn high. They demand PROFIT from you getting sick.
Here's a few articles that do address some of these things unlike yours:
