Until we come to grips with what will likely be a post-labor world, this is a good transitional approach. The 40 hour week is an arbitrary standard, and it may now be rational to reduce that number. Few jobs are now so arduous that 70 year olds cannot perform well. We are suffering from outdated standards for work weeks and retirement age, and un-sticking our assumptions is likely to benefit the situation.
