The answer appears to be - hardly anyone - how did this happen?
Is this only an American problem?
As I "age" (not that I would admit to doing so) I find that many people I know that are in their 60's would like to keep working, I expect to work until 75 or 80 or longer. What if this were the new norm?
Perhaps the hours could be reduced - the benefits reduced and the work - aided by technology - need not be any less strenuous than if done by someone who were 55 or 60.
What incentives could be provided to encourage this?
What new methods of learning would be needed?
Are there any correlations between health and working?
