Foxconn Technology Group, the company that produces the Amazon Echo, has been accused of continuing to allow abusive labor practices. Last year, the firm was criticized for employing high school interns and demanding they work unlawful overtime, in order to cut labor costs. Both Amazon and Foxconn responded to critics by promising to improve factory conditions and follow labor laws. The most recent investigation into this matter by China Labor Watch has uncovered that the firms have not followed through, and have actually decreased wages in the factory by 16 percent.
