This bill says simply that from this day forth those wishing to immigrate to America shall be admitted on the basis of their skills and their close relationship to those already here … The fairness of this standard is so self-evident that we may well wonder that it has not always been applied … [The previous system] has been un-American in the highest sense, because it has been untrue to the faith that brought thousands to these shores even before we were a country."—President Lyndon B. Johnson, from his Remarks at the Signing of the Immigration Bill, Liberty Island, New York, October 3, 1965 How did the change described in the excerpt directly affect postwar America? It encouraged internal migration. It spread factories to the suburbs. It increased international migration. It prevented diversity in the suburbs.
