"There is not a single example of a country opening its borders to trade and ending up poorer.”

“The message from history is so blatantly obvious, that free trade causes mutual prosperity while protectionism causes poverty, that it seems incredible that anybody ever thinks otherwise. There is not a single example of a country opening its borders to trade and ending up poorer.”

~ Matt Ridley from his book: The Rational Optimist: How Prosperity Evolves
