Social Security is nothing more than an income tax collected under the 16th amendment of the constitution. It was never meant to pay out because the original age at which you could collect SS was the average age of a human being. In simple terms people died before they could actually collect any real amount from the treasury. So I will lay odds on the government raising the retirement age to 73.
All taxes collected by the federal government go to the same treasury account or pile of money. Now after the Federal Reserve act it all goes the the private bank conglomerate known as the Federal Reserve Bank. So ask yourself this. If the U.S. is so broke how come the Federal Reserve can still loan money overseas?
