I wonder how much his reach of influence was increased by his nephew, Edward Bernays, who used his uncle's ideas to create psychologically powerful advertising campaigns. At one point, he wanted to promote one of Freud's books, but Freud thought the idea was vulgar. Bernays had relationships with psychoanalysts (a new field back then) here in the states who helped him in his advertising campaigns. Just seems that his theories were used for a lot of negative things, including consumptionist propaganda.
