What kind of man says dopey things like "only fools or worse..." when it is he who is the fool? And worse.
Look in the mirror Mr President!
The clip below from the National Review (you have to scroll down) is the fact of the postal rates matter, in the calumny that Trump is hurling at Amazon. (Amazon allegedly getting below market postal rates hence "cheating" the tax payer).
Given Trump's additional claims that Amazon is tax dodging (it's not), and that it's affecting Main Street retail (it's not), his Twitter storm amounts to an unprecedented and disgusting display of personal spleen...
Package-delivery rates are set by the U.S. Postal Service in negotiation with Amazon, the service's biggest customer. Despite the president's claims, the postal service does not lose money on every package delivery for Amazon. The 2006 Postal Accountability and Enhancement Act made it illegal for the postal service to charge a price for package delivery that is lower than the cost of making the delivery. All changes to delivery prices have to be approved by the federal Postal Regulatory Commission, which has five members; no more than three members can be of the same party. The commission currently has four members; three are Republicans. All members of the PRC must be confirmed by the U.S. Senate.
If Trump wanted to raise rates for Amazon, he could contact the PRC's current members and articulately effectively persuade, with evidence, figures, and reason, that they undercharged the service's biggest customer to the detriment of the American taxpayer. (Stop laughing.) Tweeting things like "only fools, or worse, are saying that our money losing Post Office makes money with Amazon!" probably isn't going to change their minds.
