the wealthiest generation in American history — a group of 67 million people 55 and older who are so affluent that the gap between them and younger people increasingly is making the USA a nation of haves and haves-much-less.

The growing divide between the rich and poor in America is more generation gap than class conflict, according to a USA TODAY analysis of federal government data. The rich are getting richer, but what's received little attention is who these rich people are. Overwhelmingly, they're older folks.

Not so for younger Americans. Households headed by people in their 20s, 30s and 40s have barely kept up with inflation or have fallen behind since 1989. People 35 to 50 actually have lost wealth since 1989 after adjusting for inflation, Fed data show.

Social Security and Medicare increasingly are functioning as a transfer of money from less affluent young people to much wealthier older people.
