One Mighty and Irresistible Tide is about how immigration law has changed over the decades, primarily between 1924 and 1965 but also more recently.
Jia Lynn Yang studies the men in positions of power that determined what American immigration law should resemble. She shares their upbringing, private letters, and the context in which they acted.
Wilkerson argues that many of America’s problems elsewhere labelled as Racism, or Systemic Racism derive from an unacknowledged caste system. She suggests that we, as Americans have an unwritten code of conduct imprinted on us by centuries of history and that this code instructs our assumptions, behaviors, and values.
In order to better understand caste, she travelled to India and met with people from high and low castes. And she studied the Nazis’ attempts to copy American law to create their own short-lived racial hierarchy.
