Overpopulation, as it pertains to America, is driven by our immigration laws. There are many factors to consider in response to the Nov. 12 letter, "Overpopulation a worldwide problem" and to other Opinion pieces on the topic recently.

As a political liberal from a family with many recent immigrants, I worry about the growing ethnic and racial animus in America. But I don’t agree with liberals who think the solution is more shaming, more scolding, more teaching tolerance programs, more amnesties for people who defy our laws, and more immigration. The answer to this growing animus lies in our own history: restricting immigration.

In the early 20th century, America suffered from anti-Semitism as well as anti-Irish and anti-Catholic sentiments. There were also extreme income disparities and immigrant ghettos characterized by poverty and crime.

In the l920s, we passed immigration laws that severely restricted immigration, creating labor shortages that drove up wages for all Americans, giving us the middle class. When everyone was prospering, our feelings changed. We elected the grandson of an Irish immigrant to the White House in l960, which would have been unthinkable in l920.

Restricting immigration is good for both immigrants and the native-born. Continuing current policies that force everyone to compete against each other in a race to the bottom is a hateful idea.
