The ONLY tax money paid to USPS is for an annual repayment of the difference between
profit and non-profit standard mail, and payment for government franked mailed.
Both are mandated by Congress which included the funding of both.
Yell at congress if you don't like non-profits getting that discount.

First Class mail is required (by law) for bills, invoices, and personal correspondence.
Again yell at your congress critter if you want "Joe fly by night" delivering some of your mail,
and "Snuffy smiths co" doing some of it. Expect to pay more.

You now have the option of automatic payments, Internet payments, and email.
I recommend those for you. So please stop buying stamps, take down your mail box, and watch your blood pressure go down.
