President Trump is right that Amazon’s operating strategy is disruptive and harmful to American businesses, argues Damon Linker of The Week. The response by many liberals to automatically criticize him over this issue is unfair. Amazon has achieved dizzyingly fast growth in recent years thanks to tax avoidance and competition-killing business practices. The book publishing industry, in particular, has been ravaged by the online retailer’s decision to promote the sale of used books, rather than new ones. This deprives already-suffering publishers and authors of vital revenue that makes their work unsustainable.
