Lind, Michael: "Free Trade Fallacy" by Michael Lind, New America Foundation. "Like Britain, the U.S. protected and subsidised its industries while it was a developing country, switching to free trade only in 1945, when most of its industrial competitors had been wiped out by the Second World War and the U.S. enjoyed a virtual monopoly in many manufacturing sectors." New America Foundation, – "Free Trade Fallacy" January 2003
Lind, Michael:"The revival of Europe and Japan by the 1970s eliminated these monopoly profits, and the support for free trade of industrial-state voters in the American midwest and northeast declined. Today, support for free-trade globalism in the U.S. comes chiefly from the commodity-exporting south and west and from U.S. multinationals which have moved their factories to low-wage countries like Mexico and China." New America Foundation, "Free Trade Fallacy" January 2003
