Where did you hear that SS returns only 2% to its recipients? A few years ago, anybody who paid into the system at the maximum rate and retired at age 65 would receive his or her entire "investment" back within 20 months. Retirees now receiving SS payments will tell you their returns are at least 10%, and much greater for those living past their life expectancies.
Persons who die before starting to receive SS are the only signigicant group of losers in the SS system. Republican Party sponsored bad mouthing of SS just doesn't have any basis in fact. None!
