Ron Paul, via his website:
The government itself runs a fraud much bigger than Madoff’s. Our Social Security system is the very definition of a Ponzi, or pyramid scheme. If the government truly had an interest in protecting people’s savings, they would allow people to opt out of Social Security altogether. We would cut wasteful spending, such as our overseas empire, to honor current obligations to seniors, and eventually phase the program out. Instead, as with Enron and Sarbanes Oxley, I expect new, unrelated legislation to be proposed that further damages freedom in the name of protecting us, amidst loud proclamations that they have made the world safe.
