Most people can recall how the Democrats have been wailing and knashing their teeth for the last 30 years about how the eeeeeeeevil Republicans are going to bankrupt Social Security. Now they turn around and say that it is solid a Sears. Folks just are not going to buy that.
You can make the math say whatever you want. But Social Security, as currently configured, will get much more expensive over the next thirty years. Not only will the demographics mean more recipients, but the amount going to each recipient is going to more than double in constant dollars, based on the formulas now in place. Something's gotta give.
Just because FDR thought it was a good idea back in 1943 does not mean we have to stick with the same program forever.
That's what the dems are counting on. If they let it go to a crisis, they will at last get their beloved tax increase. If it gets fixed, the urgency to raise taxes will be gone.
