At 2.3% per capita real income growth, real income doubles every thirty years. That is, we can expect our kids to be roughly twice as rich as we are. In particular, we should stop worrying about them supporting twice as many retirees per capita. We should also stop worrying about their environmental legacy. They will have twice as many billions to devote to environmental cleanup and upgrade even if population remains constant.

One thing that would cause the social security crisis to come back in spades would be if, as is proposed in the UK, that social security is indexed to wages instead of prices. If wages are used, social security payments will double when wages double and longevity and early retirement will bear down on workers.

How much do we owe retirees? Is it the same absolute standard of living as they had when they were working? Their same relative position in the economy? These are expensive moral questions. But recognize a promise of a wage indexed gain for what it is: it is a heavy tax on the working to give more real dollars to the retirees than they gave to the retirees while they were working.

I am still in favor of privatizing government pensions, but that would in effect be a huge cut in subsidization of government borrowing. That is, without the whole social security trust fund invested in government bonds, it will be more expensive to finance government borrowing. That will either require higher taxes, increased borrowing or reduced spending to offset.

One thing I can say about that is that my daughter’s generation will be twice as able to deal with it as mine per capita.
