U.S. auto sales are expected to languish for decades, due largely to baby-boomer generation retirement, Jerome Corsi's Red Alert reports.

Baby boomers helped to nearly double the demand for new passenger vehicles in North America from the 1960s to a peak of 17.4 million cars over the last decade.

"This year, however, auto sales in North America are projected to reach only 13 million vehicles, up from 11.9 million vehicles in 2009, largely because 'unfavorable demographics' are expected to dampen vehicle demand for decades to come," Corsi wrote.

He noted the effect of the aging baby boomers is likely to be apparent in 2013 when the number of drivers 60 years or older surpasses the potential young vehicle-buying population.

The only bright spot for the U.S. auto market is that nearly half the 250 million cars and trucks on U.S. roads are at least 10 years old, meaning replacement vehicles will become increasingly necessary, he wrote.

"While the Obama administration took over Chrysler and GM to prevent bankruptcy, the U.S. auto industry's problems are far from solved," Corsi noted.
