That may well be but it was a stupid move to cut that particular tax in the first place. It was never going to spur any economic growth [and it didn't], but it did put Social Security into an even worse situation.
They claimed it wouldn’t reduce the calculation for benefits, but I don’t believe them.
Agreed. If shortchanging SocSec “trust” fund was to be stimulating, it would have made more sense to drop the 2% from the employer side. But it was done to replace the Making Work Pay credit using budget tricks, since I am sure messing with SocSec didn’t count.
