Dependency ratios (the number of workers compared to the number of people dependent on workers) may actually be lower than they were in the 60s simply because fewer people are having children. Even if that weren't true, the idea that we have to keep putting the age up is predicated upon productivity remaining static. Productivity has gone up consistently and will likely continue to go up. Curiously some people are breathlessly optimistic about automation when it's a convenient scapegoat for high unemployment but immediately lose all faith in it when it comes to social security projections. These people probably don't have our best interests at heart.
