That’s completely beside the point. I agree the government sucks with money, but believe me, you missed the point big time.
Social Security is an annuity. An annuity is an insurance program against getting too old.
The basic theory behind annuity insurance is that it ensure you will have some income no matter how old you get. Like all insurance programs, it is therefore a gamble. If I never have a car accident, my paying car insurance was a bad gamble. If I do have a bad car accident and my car’s written off, I will recoup more in the payout than I pay into car insurance in 15-20 years. Annuities are the same thing. If you die at 68, well, Social Security was a pretty bad investment. Or if you die at 99, it was a really, really good bet. (or if you become disabled at 34, it was an awesome bet.)
The problem with insurance programs is the problem of adverse selection. Basically, the problem is that if insurance is voluntary, then the people who buy the insurance are likely to be the people who will NEED the insurance. People with expensive cars and long commutes who drive fast and enjoy road trips will buy more insurance than people who don’t drive much; people with health problems will buy more health insurance than people who have a clean bill of health. Annuities are the same; people who lead healthy lifestyles and expect to live a long time will be more motivated to buy annuities than people who drink and smoke and, like my father, fully expect to be dead by 70.
Insurance programs work better when everyone is involved. That’s why you tend to get better health insurance deals from an employer plan than you do on your own; if you personally approach a health insurance provider, they will rightly be suspicious, since** the very fact you want health insurance is a reason to suspect you have health problems. **But if RandomCorp with 500 employees negotiates, the health insurance provider can assume that 500 people probably have an average health level that’s roughly the same as the population, and offer better rates. Better still, of course, is if the ENTIRE population is involved, which is why Canadians don’t actually spend more more than Americans do on public health insurance even though the coverage is universal; the American system insures the very people who’re likeliest to gobble up the most health care.
If Social Security is optional, people who have no expectation of collecting it, or who don’t expect to collect much of it, will drop out. People who DO expect to collect a lot of it will stay in. So the average cost of a Social Security benificiary will go up, because the people remaining in the program will be likelier to be long term recipients. Perversely, you would be punishing the people who are prudent with both their health and their money. That means the government would either have to jack Social Security contributions up, drop the payments, or go further into debt (or jack up taxes elsewhere.) It would have to become a much larger transfer of wealth from young to old, at least among the participants, which right now is a case of solving a social problem that does not exist; by and large old people are not an economically troubled group in the USA.
