I enjoyed your response.  There are two studies that I've seen that calculated the time needed to receive back the individual contribution.  Each of them had a "person" who paid the maximum into SS for their entire career and retired at their retirement age of 66.  One had a "person" receiving their contribution in 4.6 years and the other study in 4.86 years.  Double it to include the employer contribution.  After that time, the taxpayers are paying their SS.  It's so easy to calculate because at the bottom of SS statement is printed the amount contributed by the individual and the employer.  I did mine and I'm presently being paid by the taxpayers.  Take care.
