Josh's take is exactly right. There was something I was going to write the other day but the post got too long so I didn't. It was going to be something like this:
The one reason to "fix" Social Security, that is come up with some long term funding plan which closes the "actuarial gap" until the end of time, is too shut Fred Hiatt and the gang up once and for all. But we'd be naive to think that such a fix would do anything like that. As long as the social security haters argue that the trust fund isn't "real," adding more money to the trust fund does nothing to further that goal.
But, anyway, Josh put it better. So go read the link.
