10-12-26 Depopulation: What Happens When the Population Shrinks? The Bill King Interview

King describes fertility decline as a broad trend rather than a China-only policy outcome: China’s births were falling before the one-child policy and continued to fall after it ended, while Japan and Korea had similar trends. He says global fertility dropped from about 5.5 children per woman in 1970 to about two, and cites women’s education as a major factor.

The speakers connect population momentum to a shifting geopolitical balance: one projects that India could keep growing for another 30 or 40 years and reach twice China’s population by century-end, changing the regional dynamic. Separately, King reports a UN projection that China could lose half its population by the end of the century, while noting Professor Lutz thinks the decline could be worse.

King says immigration could temporarily offset depopulation, but expects countries eventually to compete for immigrants; he also says Latin America’s near-replacement fertility and improving economies may limit migration north. He puts the U.S. foreign-born share at 18%, within the 15%–20% range where he says backlash typically emerges, while a separate hypothetical proposal suggests admitting 2 million vetted, skills-prioritized immigrants annually.

The speakers say pay-as-you-go pensions face growing pressure as the worker-to-beneficiary ratio has fallen from 16 in the 1930s to fewer than two today, with longer lifespans adding to retirement costs. They link that strain to broader fiscal and funding challenges, citing U.S. debt of $40 trillion, Japan’s debt at 230% of GDP, and the effect of men leaving the workforce on worker-funded systems.

The speakers say raising a child to age 18 can cost $250,000 to $300,000, and King argues that student-loan burdens can make it harder for young adults to buy homes and start families. The host asks whether recent affordability pressures may also have contributed to delayed or smaller families; separately, King says recent data suggest housing prices have topped out and are probably coming down quickly.
