Social Security is one of the U.S. government's most successful programs. It has a solvency life of more than 20 years, currently.
When one lives in a society, one makes the bargain of living according to that society's conventions. Long ago, before you or I were born, and clearly skipped by your history books, to live passed a certain age in this county was an abysmal concept. It's the Appalachian mountains, it was not uncommon for old folks to be lead into the mountains to die. Each region had it's own cruel means of letting old people die when they could have been cared for.
What you are forgetting is that our nation decided that it was no longer acceptable to allow old people, who worked hard all of their lives, to die miserable deaths with no care, health or otherwise. We chose to use our system of taxation to create a safety net for those who built our country before us, and made it was it is for us, a hand, nay, a repayment in the form of a tiny sum of money to help them have a decent quality of life.
It is not a perfect system, but it is neither wrong nor broken. If you don't think it's fair, it's because you're short-sighted. If you worry that it won't be around for you, pressure the republican officials who want to destroy it. Hundreds of leading economists have come out, squarely, against privatizing SS because of it's volatility that I won't argue here; Suffice it to say, they no more about economics than you or I.
Quit your bitching about what's yours and make a choice to worry about what is everybody's and how it can be better.
