I am happy to see others making the point I have tried to make for years: That the coming financial problems with Social Security are not its biggest problem. Megan McArdle and Clive Cook say it very well:
In this post on Paul Krugman and Social Security,
Clive, as usual, targets with laser accuracy the real problem with the
Social Security system: not that it is bankrupt, but that it encourages
people to make extremely bad decisions about providing for their future.
It starts with childbearing: social security systems seem to exert downward pressure on birthrates,
in effect undermining their own actuarial base. Social security
socializes the benefits of childbearing in providing for retirement,
but no one has yet figured out how to socialize the main cost, which is
turning your life choices over to a screaming pre-verbal dictator.
People are thus tempted to free ride on the childbearing of others, and
the more generous benefits are, the more they seem to free ride. This
is one reason that Social Security, which used to have more than 30
workers for each retiree, now has only three, headed towards two.
Social Security also encourages people to leave the workforce
earlier than they otherwise would. People are healthier than ever at
65, but while in 1950, almost half of all men over the age of 65
worked, that number is now less than 20%. This appears to be highly
correlated with the spread of defined benefit pensions such as social
security, which offer no advantage to delaying retirement. Indeed,
Social Security perversely penalizes anyone who takes early benefit but
continues to work, docking a third of their earnings.
Finally, Social Security discourages private savings. This is
terrible for two reasons. If future fiscal problems force the
government to reduce benefits, the people who didn't save enough
because they relied on those promises will be made much worse off than
they would otherwise have been.
The other problem is that Social Security is not a productive
investment. Privately saved money is mostly lent to corporations that
mostly use the money to do things that make the economy more
productive, such as R&D and capital equipment upgrades. Social
security "contributions" are lent to the government, where they are
mostly spent on things that could not be remotely described as
improving our economy's productive capacity, such as farm subsidies.
