In peace as in war, there is no point wasting time and resources attacking heavily defended enemy positions that you don't have to take.
Social Security and Medicare are supposed to be among the most difficult programs to cut without ruinous political consequences. However, it is not necessary to attack all the spending on these programs in order to make big savings.
Instead of attacking these programs as a whole, what is far more vulnerable is the compulsory aspect of these programs. If Medicare is so great, why is it necessary for the government to force people to be covered by Medicare as a precondition for receiving the money they paid into Social Security?
Many people with private health insurance would rather continue to rely on that, instead of being trapped in Medicare red tape. It is not a question of taking away Medicare but allowing people to opt out, saving the taxpayer from having to subsidize something that many people don't want.
It is not a question of forcing people off Social Security either. But private retirement accounts can offer a better deal.
Even someone who retires when the stock market is down is almost certain to get a bigger pension from a decent mutual fund than from Social Security.
By giving young people the option, while continuing to honor commitments to retirees and those nearing retirement age, the sob story defense of runaway spending can be nipped in the bud.
