The mail moving slower (in your opinion...I'd like to see some proof) is not only an "unmitigated disaster", it's also more of a disaster than what's going on with the airlines which you ranked #2?
Waiting for hours on the tarmac, a real need for a "Passenger's Bill of Rights", almost having mid-air collisions, security lines, "no-fly" lists with U.S. Senators on them, no frills transporation, etc. Thousands of lives at risk.
Waiting an extra week or two for a bulk-rate "Shoreliner" mailed during the holiday season.
