President Donald Trump has made it clear in recent days, through his usual medium of Twitter, that he believes Amazon is harming the U.S. economy
. He expressed particular concern regarding physical retailers inability to keep pace with Jeff Bezos' behemoth, in addition to criticizing its use of the U.S. Postal Service. Many of these complaints are not new, such as Trump's claims that Amazon has an unfair competitive advantage because e-commerce operations have not been required to collect state or local sales taxes.
