You know, if I had all the FICA money that went to the Feds on my account over the years, either with interest applied or inflation-adjusted with a reasonable real interest rate added, my personal savings would be even healthier than they are. The reason people like me don't want to have Social Security and Medicare stripped is that we have been forced to pay for these all of our working lives, and we think we deserve at least something of what we paid for.
Sorry, but you were robbed. You didn't "pay in" to anything - you money was taken and given to your grandparents (as well as being spent by politicians to buy votes).
You can justly complain all you want about how unfair this is, and you can try to take up the issue with the people who actually robbed you, but you have no right whatsoever to inflict the same robbery on your descendants. They aren't the ones who robbed you, so they aren't responsible for it.
You also had your entire life to prepare for retirement, and at ample warning going all the way back to the 1980s about how the system was financially unsustainable, so if you didn't heed the warnings and aren't prepared now, that's also not your descendants' fault.
