What they should do is review the subsidization of Chinese companies shipping to U.S. customers, often at the expense of makers and merchants in the U.S.:
According to the terms set out in Universal Postal Union treaty, the USPS in 2014 gets paid no more than about $1.50 for delivering a one-pound package from a foreign carrier, which makes it hard to cover costs. [1] The USPS inspector general’s office estimated that the USPS lost $79 million in fiscal year 2013 delivering this foreign treaty mail. (The Postal Service itself declined to provide specific figures.)
In an effort to ride the e-commerce boom, the Postal Service signed a deal in 2010 with China’s state carrier to sell a special service for small packages entering the U.S. For a small premium, the USPS offered tracking and delivery confirmation, an essential feature for online retailers, as well as expedited shipping.
... In 2012, USPS was paid only 94 cents on average for each piece of Chinese ePacket mail, according to a February report from the Postal Service’s inspector general’s office. That report estimated that the Postal Service was losing about a dollar on each incoming item, adding up to a $29.4 million net loss in 2012.
Forums on eBay are filled with angry notes about ePacket. “I must say that it is simply an economic disaster for US Sellers,” one person wrote. “One product that we sell for 2.00 with 2.50 shipping a chinese company is selling for .99 with free shipping,” another complained.
