Paul Erhlich's Population Bomb was a call to arms in 1968. His prophecy of congestion and resource depletion motivated a generation in their child-bearing years to address exponential population growth. This generation responded to the call. Population became the central focus on our first Earth Day in 1970. Concerns over population growth permeated the media and seared an indelible mark on the collective conscience of a nation.

The U.S. fertility rate dropped as a result of environmental awareness of population pressures and other factors. These other factors included improved family planning, female empowerment, urbanization, increasing costs of child-rearing, and rising college expenses. Our concerns reflected an interest to leave a more dignified future.

Between the mid-1960's and the mid-1970's, U.S. fertility rates plummeted from 3.5 children per women to 1.7. Replacement level fertility is 2.1 children per woman. In other words, if every two parents produced an average of 2.1 children, then the nation would stabilize. At 3.5 children, the population would continue to explode. At 1.7, a generation of children no longer fills their parents' shoes.

Fertility reductions eventually lead to an "aging population." This is documented in a study by the Population Division of the United Nations Department of Economics and Social Affairs. The UN study is found in a booklet entitled Replacement Migration: Is it A Solution to Declining and Ageing Populations? It can also be accessed at

Table I.2. of the UN study reveals what happens when the populous baby boomers decided to have fewer children. In 1995, every pensioner in the United States was supported by 5.21 workers. The "dependancy ratio" of pensioners to workers was a favorable 5.21 to 1. The mid-range projection for 2050 reveals only 2.82 workers per pensioner. By reducing the number of births in the 1970s, each retiree in 2050 will impose almost twice the load upon each worker. The rising costs of ever-expanding medical care will also add to the workers' burden.

The UN study points out that there are essentially two ways to lighten the load for workers in 2050: we can postpone the retirement age or we can increase the population with more workers.

Just how far will we need to postpone our retirement age to preserve the 1995 dependency ratio between workers and retirees? According to the UN study (Table IV.10.), by 2050 a retirement age of 74.3 years will preserve the 1995 dependency ratio. And just how much immigration will be needed to preserve the ratio if we would insist on retiring at age 65? According to the UN study, between 1995 and 2050, an additional 593 million immigrants would be required to maintain the ratio if the retirement age is to remain constant at 65. That comes to almost 11 million immigrants per year (i.e., about ten times the unprecedented wave of immigration now fueling our resource depletion and congestion)! The United States would have to become a nation of a billion and as populous as China and India for the baby boomers to claim the same retirement age and dependency ratio as their parents.

The UN study identifies a defining challenge for the nation once committed to reducing congestion and preserving natural resources. It specifically imposes a pivotal decision on the generations having reduced their fertility in the 1970's and beyond: Will they maintain an allegiance to the bedrock principles of Earth Day 1970? Will they be willing to roll up their collective sleeves and postpone their retirement age? Will they allow the U.S. population to begin a slow decline, with a view toward stabilizing at some future point? Or will they insist on retiring at 65 and lay the groundwork for the U.S. to become the next billion person nation?

The unprecedented rate of immigration since 1990 lulls us into a Ponzi scheme. Each succeeding generation strives to sustain itself on the shoulders of ever-burgeoning recruits lodged in the queue behind it. We teeter on the brink of a new day for the nation. Will we choose to become good ancestors by postponing the retirement age? Sixty-five was established by German Chancellor Otto von Bismarck when the world's first social security system was created in the 1880's. Life expectancy then was 45 years. By contrast, today's 65 year-old retiree looks forward to decades of social security support.

According to Hardin's Law "We can never do merely one thing." When the 1970's child-bearing generation decided to leave a less congested future, it could'nt do just one thing. It did not just plan for less congestion. It did not just conserve natural resources. This generation also established a test of its resolve in the elderly years. Will it make a lasting peace with its founding principles by postponing the retirement age? Or will it cash in the chips?
