Not necessarily a bad thing. Take this quote from the Milwaukee Journal Sentinel:
"The beauty of Social Security to me is that all the money (that goes to retirees) goes right back into the economy," says Stephanie Sue Stein, director of the Milwaukee County Department on Aging. "It's money that is being spent, which is why we're never going to have another Depression."
Social Security covers 50 million people today. By 2030, it could be 84 million. (Journal Sentinel)
