Yes with 43 million unwanted children, less has been paid out in public benefits, and less crime. Of course we have imported 10 million illegals to help take their place. I suggest stopping illegal immigration before trying to stop abortions.
SS is a Ponzi scheme, more people paying in just means it will last a little longer before it breaks...doesn't cure a thing.
Actually, I was thinking more in terms of the lost taxes of 43,000,000 potential wage-earners being fed into the Social Security fund, and the children of those wage-earners, etc.
