Why shouldn't Social Security age be raised for future generations?

112. First and foremost, increasing the labor pool diminishes wages

The need for labor dwindles on virtually all levels, some will call out a few fields with needs knowing full well the number is insignificant against the available potential labor.
The systems is not designed for high unemployment and flat or declining wages.

Much of the difference is child mortality, I would guess a decline in massive war casualties, and keeping the ill alive longer.
Outside if that you are pretty much saying Social Security and Medicare are themselves a problem of keeping useless eaters alive too long.

Whatever you thoughts on the make up and validity of "living longer", you and no one thinking along the same lines ever identifies the potential medium or even long term need for the additional labor and sure as hell never want to discuss the hit in wages over lifetime.
67 is pretty much batshit crazy as it is. A lot of folks are wore the hell out, are not in any demand, and add availability to a labor market that can never be expected to approach full employment without crashing wages, if then. Thank God it isn't effective right now but there is virtually no reason it won't be stupid when it happens.

I also wonder why some feel we need to work the last bits of productivity from our citizens, tax them for decades, and then build a system that hopes many will die at their post as not to payout?

Nobody is being made to retire if they want to work, are capable, and are in demand but this bullshit about not wanting those that aren't in as swell of a place to put it down and enjoy some years in some health and peace.
