The calculation does not take into account the number of people who are not looking for a job. If the number of people who are not looking for a job over time changes (which it does), the comparison is skewed. As the article points, it is also difficult to compare over time because of changes in the age makeup of the population.

2. on a pension
3. SSI or welfare or Social Security
4. Had savings and investments.
No able bodied person I've known in my entire life 'dropped out of the work force".
who are these 'discouraged workers' ? I've never met one. Some might take a year, while on unemployment, but it runs out and the are forced to do something about it.
