This leads to the paradoxical situation that as a percentage of GDP, those irreducible-labour sectors begin to loom larger and larger.
If you are going to dismiss a (very middle class, by social standards) dude, at least you should do a little bit more than hand-waving.
Here's the simple way to think about pensions/SS: we take about 4% of GDP and cut checks to old people. They buy food and pay their rent. Nobody starves. It always works, in 1961, 2011, 2061, whenever. Anybody who says otherwise is trying to fool you.
With unemployment at such a high level today, increasing the retirement age would keep all of the baby boomers employed, rather than leaving the work force. It does not look good any way you look at it.
However, the back to the problem with taxing jobs out of existence: fortune is on youths side. As bad as the problem may sound, once the problem hits criticality, you get a sudden societal upheaval and things right itself immediately. No one should count on their pensions as being forever.
