In light of Drew’s last post, here’s Krugman in 1996:

“In 2010 … the boomers will begin to retire … The budgetary effects of this demographic tidal wave are straightforward to compute, but so huge as almost to defy comprehension … Yet if you think even briefly about what the Federal budget will look like in 20 years, you immediately realize that we are drifting inexorably toward crisis; if you think 30 years ahead, you wonder whether the Republic can be saved.”

Props to National Review online’s Donald Luskin for unearthing that one.
