"Since we enacted the Social Security Act back in 1935, Congress has recognized the necessity to "make more adequate provision for aged persons . . . through maternal and child welfare . . . and public health." Those are the words of the Congress--"more adequate." The time has come, I think, to make it more adequate. I believe we should increase social security benefits, and I am so recommending tonight. I am suggesting that there should be an overall increase in benefits of at least 13 percent. Those who receive only the minimum of $55 should get $80 a month."
