I think raising the retirement age to 69 by 2075 is too little, too late.
Something to keep in mind here is that there's a whole other side to this equation that's part of the plan, too. In addition to raising the retirement age, there's no question that the U.S. government will be reducing Social Security outlays by reducing cost-of-living adjustments (COLAs) -- either directly, as stated in this commission's recommendations, or indirectly, by artificially understating the inflation rate every year as they've been doing for the last couple of years.
