Young people particularly, aren't stupid enough to want to see themselves suckered into the same program that screwed their grandparents over. That's why a private account is making more sense to them. You speak of where all the money will be for those about to retire? That, in fact, is a very good question to bring to your Federal Government entrusted with your social security savings. Where exactly IS all that money now?
I am a grandparent. I've been collecting Social Security for over eleven years and barring a medical catastrophe I'll be collecting for another ten or fifteen years, which means I will collect a hell of a lot more than I (and my employers) contributed. I don't think of that as being "screwed over."
Could I have done better if I'd put that money into some private investments? Maybe. But I also could have done a lot worse. Because first of all I know nothing about investing, nor to I wish to know more about it -- and I am by far not the only working class American who feels that way.
I also invested in U.S. Savings Bonds for most of my working life and I have a nice little stack of those. Like Social Security they don't pay off as well as some other bonds I could have bought, but as with Social Security I opted for the absence of risk.
My entire financial situation is based on advice I got from my parents and grandparents, who suffered through the Great Depression. They emphatically warned us against private investments. They advised us to take civil service jobs with good pensions, avoid debt, and invest in nothing but Government bonds. I followed that advice to the letter and I have absolutely no regrets. I'm doing just fine.
If you believe what your Libertarian mentors have told you, all I can tell you is I live in a very large Retirement community in New Jersey (Leisure Village) and I've met several people here whose private investments were either nearly or completely wiped out in 2008 and were it not for their Social Security supplement would be living off their children or welfare. I
wish I could put you in touch with them so you could hear what they have to say.
One thing I know about investing is returns are predicated on level of risk. I'm one of those who prefer a sure thing. And, unlike you and most other Libertarians I believe Social Security is a good thing, I have faith in it, and I know that anyone who is content with ordinary comforts and reasonable luxuries can have them by avoiding the fast lane and playing it safe.
