It's no secret that Americans are in denial when it comes to aging. Sales of Botox are booming, tummy tucks and eyelid lifts are common, and anti-aging creams and gels are multibillion-dollar businesses.
So it should come as no surprise that Americans find it difficult to grasp that our population as a whole is maturing, that the median age is slowly climbing upward. This has serious consequences for our economy and our culture, and it also bears on the immigration issue now being debated.
To understand the demographic challenge before us, consider the baby boomers, that massive generation born roughly between 1946 and 1964. The eldest of the boomers are beginning to retire.
And guess what? We don't have enough people to replace them in the labor force among native-born succeeding generations. Nor do we have enough low-wage workers to serve all their needs in retirement - and boomers are anticipated to be a highly active set of retirees, living longer and with more demands on the economy than their parents ever called for.
In other words, we need workers, especially low-wage ones, and we have not bred enough of them in-house, so to speak.
Immigrants can fill these needs now and in the future.
Far from the glib rhetoric that has hindered efforts to pass immigration reform on Capitol Hill, saner economists have argued that importing more workers is vitally necessary. In fact, in congressional hearings, they talked themselves red, white and blue in the face about it.
Granted, these arguments can be dry and abstruse, not nearly as thrilling as, say, the gloom-and-doom oratory of a Lou Dobbs or your average Minuteman. But what's really more important to the nation, "cultural" purity or economic well-being?
The U.S. is in a race to stay competitive with foreign countries, especially emerging powerhouses such as India and China. Our strength and competitiveness in the future depend in part on our ability to maintain a high ratio of workers to retirees.
Despite much commentary to the contrary, the U.S. economy is healthy. We continue to add jobs. And the unemployment rate is about 4.4 percent - far below the 5.7 percent average unemployment rate in the 1990s. So, despite all the angst about immigrants "taking" jobs, the truth seems to be that they are merely filling jobs.
There are, of course, sectors that have been unfairly hurt by illegal immigration - the construction industry is a prime example in which wages have been somewhat undercut and U.S. workers have been displaced. But that merely demonstrates why we need immigration reform - to control wages and the imported laborers' impact on U.S.-born workers.
I'm always amazed, when talking about immigration, that so many well-educated people are oblivious to the various levels within our labor force. They are grooming and educating their children to hold professional, well-paying positions. Which is fine - the U.S.-born public should strive to be highly educated, and we are more so than past generations. But these same folks seem blind to the idea that we will always need many, many low-wage workers - that the economy as a whole does not turn on the labor of doctors and nurses and the highly skilled alone. Someone has to take out the trash, mow the lawns, wash the dishes, pick the crops, paint the houses, cut up the pork loins and gut the chickens.
In the end, all the huffing and puffing about "illegal alien invasions" won't alter the facts of birth and death. Baby boomers, you are aging. And how you spend your golden years depends in no small part on how we deal with immigration today.
