The United States needs immigrants. Americans aged 65 or older will nearly double to about 50% of the population from today’s 27% due to declining fertility and rising longevity. The dire warnings we hear about the Social Security and Medicare systems will come true with a vengeance. Immigration, to be sure, is not the only remedy for our demographic problems—we can incentivize child-raising and extend the average working life—but it is an indispensable one. Working-age adult immigrants who pay into the Social Security and Medicare trust funds help keep these systems solvent.
The fall in America’s fertility rate stems from cultural and religious shifts that cannot be undone quickly. In a January 10, 2022 contribution to The American Mind, I reviewed the statistical evidence that the decline in our fertility can be explained by the attenuation of religion in the United States.
