Yes, the retirement age should be raised (though I don't know what age it ought to be raised to). 65 was not handed down on stone tablets from Mt. Sinai. USMC is right about the age statistics -- when SS was first established it was simply unreasonable to expect most elderly folks to live long enough to collect retirement benefits. Now it is unreasonable to expect them
not to.
There is simply no way to talk seriously about "saving" Social Security (the danger to which, I should add, is massively overstated) without talking about raising the retirement age. It works because it not only reduces the number of people collecting benefits, it also, of necessity, increases the number of people paying into the system.
If this means people have to start stuffing money into their sock drawer to save up for retirement, good. This nation's rate of savings are too low, anyway.
Despite living longer, people are not healthier. Most jobs are to strenuous for 70 year olds. Do you think a 70 year old should be in the sun on a hot roof putting a roof on?
I'm always being told "Americans won't do those jobs" which is why we need to throw open the floodgates to tens of millions of otherwise-unemployable surplus Third World hand laborers.
But at any rate, most jobs don't involve backbreaking physical labor. There's no tragedy in being a teacher or a computer programmer at age 70.
