Would you mind posting a credible link to where the post office is funded by tax payer funds?
I can see where it could happen if things aren't changed.
Funded outside the approximately $96 million that is budgeted annually by Congress for the "Postal Service Fund." These funds are used to compensate USPS for postage-free mailing for all legally blind persons and for mail-in election ballots sent from US citizens living overseas. A portion of the funds also pays USPS for providing address information to state and local child support enforcement agencies.
