Is McCain hypocritical to accept Social Security, but call it a scam?

I feel that anyone with the type of income that he has should not be able to receive benefits! I don't care that he paid into it, he doesn't need it! The real scam is that the government has used the money paid into S.S. for other things, they have spent the money that was to pay for S.S.! The money paid into S.S. should have been invested so that it could grow & not be depleted by the government! If this had been done the younger workers would not have to worry about S.S., the government has cheated us all for a long time! Instead of paying out trillions of dollars to aid others, they should be paying back what they have taken from S.S.!
