It's "satire"

The Onion: "76 Million Baby Boomers Abscond To Fiji After Draining Nation’s Social Security, Medicare Accounts."

According to sources, the entirety of Medicare and Social Security was slowly siphoned off as the post-war generation built trust by assuring the other 240 million Americans that they would collect their share eventually. However, since decamping, observers say the baby boomers have spent the funds on opulent lifestyles in the tropics where they intend to live out the rest of their days relaxing in comfort, all at the expense of the children and grandchildren they reportedly claimed to be concerned about.

Ha ha ha (sob).
