Bloomberg reports that Republican candidate Fred Thompson has been saying that we need to cut Social Security benefits. He also advocates private savings accounts, but has not said how private savings accounts may be achieved since he opposes a tax increase. His position sounds essentially the same as President Bush's position, which plays well with those who might vote in a Republican primary, but it is completely unworkable. If you want to carve private accounts out of the current tax rates, you are looking at massive cuts in current benefit payments and that is not going to happen, as Thompson knows well.
Democratic candidates John Edwards and Barack Obama have been proposing an increase in the cap on earnings subject to the FICA tax to bring the Social Security trust funds into long term balance. This position has been harshly criticized by Paul Krugman of the New York Times and others because it buys into the preposterous notion that Social Security is little more than a Ponzi scheme.
