No, you pay FICA taxes because you are legally required to do so.
It's NOT YOUR MONEY, and it's already been thrown away on people older than you. Good grief.
You know what that is called? A Ponzi scheme.
It is MY MONEY Jimmy.
In fact, there isn't a penny that the government has that isn't our money, ergo my money.
If you want to argue that my money has already been used on others, that's fine, but it remains my money that they forcibly took from me based on the premise that I would get it back later, so now, just like I paid for older people's benefits with my contributions, younger people will pay for mine.
If it makes you feel any better, the worker to retiree ratio is 2-1 right now.
My sons will pay for my benefits.
