@JPB,
I have kept records on social security and MediCare payments vs benefits.
No contest; the benefits have far exceeded anything we put into them. The only issue would be how my payments over the years if invested would have returned vs what social security and MediCare benefits are "worth."
Through 2011, my wife and I paid into social security/MediCare $131,413. We received (through 2011) social security benefits of $340,869. Medicare? I couldn't begin to calculate all the benefits. In 2008, I was diagnosed with stage 4 prostate cancer. I received radiation treatments for eight weeks at no cost, and my health today is excellent. I just received a note from my doctor to have a PSA test done. Our MediCare benefits? Priceless.
