Plain wrong indeed!!
Well, like all good social programmes, it is a matter of opinion. There are lots of factors and such large numbers, that I would personally say it would be ill advised for anyone to totally depend on that for retirement income.
I specifically remember the first time I got my information about how many points I had for what I earned to qualify for full benefits. The letter kindly informed me that Social Security was to run out of money the exact year I was to retire! Of course, the next year, the kind of information had been removed.
Who is to say what effect a large aging population of retirees who live longer and longer will have on Social Security. While the economic growth has been large of the past 75 years, it is likely the worker population in 75 years will be very different to the worker population of the future. People are having less and less children these days making for a large future imbalance of workers to retirees.
With politics being politics, what are the chances that they will raise the age of retirement? People have a sense of entitlement that hasn't been seen before. My grandmother still thinks that she is entitled to her money because my grandfather paid in all those years, but doesn't realize that she, being almost 90, has far outlived the money that my grandfather contributed.
