On the campaign trail, Donald Trump has railed against the effects of free trade and globalization, denouncing trade deals as bad for American workers. In his 2008 book however, Trump seemed to concede that globalization was here for good, writing, “No one can afford to be isolationist anymore.”

“Globalization has torn down the barriers that have formerly separated the national from the international markets and one result is that affluent foreigners have been drawn to real estate in the United States,” Trump wrote in Never Give Up: How I Turned My Biggest Challenges into Success, a book from Trump University.

“The important thing to consider is that more and more there is an interdependence of world economies,” he continues. “No one can afford to be isolationist anymore. For many years, many Americans have had second homes in foreign countries, and now the trend, as Penn points out, has hit our shores. This is nothing new, but it’s relatively new to us. I think it’s a harbinger of things to come, and when I first went with condos years ago, I knew it was a timely thing to do.”
