Based on nothing other than publicly available information and personal conjecture and logic:
1) The company claims the rates being offered by USPS meant we were practically going to be working for free, turning FedEx into a federal jobs program instead of a profit-seeking business. This seems similar to the basis for eliminating Amazon from our jets a few years back because no matter what Prime says..."shipping aint free."
2) Couple that with the fact that the USPS has publicly cited a impending vast shift to more trucking to help with their abysmal economics. More FedEx trucking for USPS would not have helped keep the day sort going.
3) From FedEx marketing emails in my inbox, FedEx plans to go head to head with USPS on fixed-rate guaranteed shipping that will see (in my opinion) exapanded everyday shippers bringing their junk with them to Walmart to ship vs. finding a partially staffed, extended lunch hour post offices to do their shipping. Same with small online businesses.
4) With regard to commuting...just a question for Henny Penny doomsdayers...Isn't most of our week-on/week-off flying night hubturns? I get it--people who have flown days for two decades are terrified of night hubturns. But if the number of commutes is the concern--night flying=fewer commutes from my toplevel perusal of bidpacks.
What's wrong with being an optomist? Is that against the rules of the forums?
