Frank Capra was an immigrant--he rejected the theories of progressivism, communism and socialism popular in Europe. ". . . he did not understand America, as many Americans do today, in terms of personal categories of identity such as race, ethnicity, gender, or sexuality. He understood America in terms of its political principles—the moral principles of America that can be shared by all who understand them and are willing to live up to them. . .
In his last and most personal tribute to his adopted country, Capra recalled his family’s arrival at Union Station in Los Angeles after their long journey across America in 1903. When they got off the train, his mother and father got on their knees and kissed the ground. Capra’s last words to his assembled audience were these: “For America, for just allowing me to live here, I kiss the ground.” Capra did not believe that he had a right to be a citizen of America. Rather he was grateful for the privilege of living in America."
