It seems to me that a country's wealth must be generated from something other than performing services for each other. We can't all make a good living by delivering each other pizzas, giving each other massages, selling junk on eBay, or stocking WalMart stores, etc..
Transisting from manufacturing to service jobs may be a race to the bottom. Even those jobs will be harder to find if people continue to work longer. I sometimes wonder what society would do with all the surplus workers if we really eliminated all the unnecessary paper shufflers in government, healthcare, and industry.
