50 years of change due to senior citizens

From Charles C. Mann’s “The Coming Death Shortage” (The Atlantic: 1 May 2005):

The twentieth-century jump in life expectancy transformed society. Fifty years ago senior citizens were not a force in electoral politics. Now the AARP is widely said to be the most powerful organization in Washington. Medicare, Social Security, retirement, Alzheimer’s, snowbird economies, the population boom, the golfing boom, the cosmetic-surgery boom, the nostalgia boom, the recreational-vehicle boom, Viagra—increasing longevity is entangled in every one. Momentous as these changes have been, though, they will pale before what is coming next.
