With regards to Social Security, I will support any legislation allowing me or anyone my age and younger to opt out.
And I will sincerely pity you when you're 80 years old and have run through all your savings. The thing about retirement is that it is impossible to plan for. Nobody knows if they will die at 40 or 100. Nobody knows if they will need years of skilled nursing home care or will pass suddenly from a heart attack without the need for much costly care. And unless you go early in a freak accident, you will have years when you're wasting away and have no capacity to work. The only way any of us (except for the absurdly wealthy) can have any kind of security in our declining years is to embrace a broad based defined pension system like Social Security. The only way to keep it is to demand it.
