Robert J. Samuelson: On pensions and Social Security, young will lose

But the calculus will be selective. To aid the young, we could tighten Social Security and Medicare, raising eligibility ages and reducing payouts for wealthier retirees. Unlikely. Younger voters seem clueless about advancing their economic interests. In 2008, 18-to-29-year-olds supported Barack Obama by 34 percentage points. They love his pseudo-youthfulness. Or his positions on other issues (immigration, gay rights) trump economics. As president, Obama has done nothing to improve generational fairness.

If the young won't help themselves, their parents and grandparents might. They might champion revising retirement programs. Dream on. Parents and grandparents may be worried about their offspring's prospects, but they're not so worried as to sacrifice their own. There are real conflicts between the young and old; so far, the young are losing.
