Well, that generation you blame did go from retirement at 65 to full retirement at 67, and that generation went from Social Security taxes at 3% and DOUBLING the SS taxes to 6% to try to save SS and keep it alive for themselves and future generations....
They did make sacrifices and efforts to strengthen it and were willing to do so, with their wallet.
And surpluses were in hundreds of billions a year for a few years. The problems arose when legislators used those surpluses to pay for what federal income taxes should have been paying for in the budget, by borrowing the SS surplus monies meant for the suring up for younger generations when their time came.... Instead they used our SS surplus to give income tax payers, the Bush tax cut....a transfer of SS monies, our wealth, in to primarily the pockets of the very wealthiest of whom SS taxes are capped or don't pay any SS taxes at all....
