Social Security is a great security blanket for society in general, and it's too bad it couldn't be left alone to provide Social Security, period.
But some politicans and government budget people always want to dip into Social Security funds for "temporary" relief elsewhere in the federal budget, and private institutions would love to get into Social Security savings and take their higher fee cuts.
The most important future consideration is having fewer workers to pay for more retirees. But some of that is a misconception too. One school says current workers are paying for present retirees. Another school says current workers are saving to pay for their own Security Security when they are eligible to draw it.
Another consideration is people living longer than they did when Social Security was created. The obvious fix for that is to not allow Social Security payouts until age 70 or so instead of 65, and none earlier as is presently allowed at age 62.
Having invested some in savings accounts, no-load mutual funds, and stocks, I can add my voice to the chorus that says BEWARE, truly there are NO guarantees of any future returns, let alone enough to live on. You might be lucky, and you might not.
A government that can make war around the world, give generously to disaster victims around the world, and give more money to support various international organizations and causes, can surely continue to provide at least a minimum Social Security network free of private enterprise profiteering for its hard-working citizens who most deserve a return on their own money.
Incidentally, it is never too early to begin requesting every five years or so Your Personal Earnings and Benefit Estimate Statement from the Social Security Administration. The good news is IF you live long enough, it won't take too many years to recover your Social Security investment.
And don't forget Medicare. You're saving for that too along with Social Security, and together they take a respectable amount of money out of each paycheck. You earn that back too IF you live long enough.
It's always about actuarial tables.
The tough thing is we all have to sit down and puzzle through the financial smoke and mirrors of people trying to sell us investments. The first question is to ask what THEY are profiting from OUR money. You might be surprised.
The second question is for X amount of money invested in Y, how much NET after tax and fee money will we receive, and how does this compare to other investments? Naturally this includes EXPECTED (rarely guaranteed) rate of return and risk, the two main balancing considerations.

The bottom line is what you need to live on in retirement, meaning NET after taxes and fees -- money you can spend on yourself.
For most people who are not wealthy, Social Security and Medicare are vital parts of retirement, and it is not likely they can be duplicated by complete or partial privatization. No commercial or private sources are as secure and reliable as the citizens' collective investment in the United States government.
