Another of those inflationary gifts that keep giving. We paid SS tax on much lower income than people are paying in for comparable jobs today, so with cost of living adjustments and inflation in wages/salaries over the years, there's no doubt you are subsidizing us. Just like we did our parents, and if you don't screw it all up, just like your children will do the same for you. BTW my generation paid for SS benefits to recipients (like our grandparents) who never paid into the system during all or part of their working years because SS came along late in life for them. My grandparents were born before 1900, my parents in the very early 1920s, and I am an original boomer from 1946. Tame inflation and we would all be getting SS payments much more commensurate with what we pay in.
For the record my starting salary in 1976 - an engineer with a MS in Nuclear Engineering was something like $17K, and I happen to remember my new 1973 Pinto (with lots of extras) was $3003. That should tell you a little bit about how screwed we are by inflation. I've watched the wage/price spiral all my working life, and all I can show for it is higher tax brackets and imported goods because we priced ourselves out of business.
