As measured by the government, you are unemployed only if you are collecting unemployment. Noted today is that over 50% of the unemployed are no longer collecting unemployment, hence we can expect the unemployment rate to begin dropping.
Also helping the numbers is the boomers facing retirement in the near future, and finding themselves out of work with no prospects, and taking Social Security at an earlier age than they had originally planned. This also works as a cost-saving measure since a 62 year old retiree gets only about 2/3 of what a 66 year old would draw.
The disadvantage of being an older worker and actually working is that by the time I get to retirement age, all the best bridges and intersections will already be occupied by folks younger and stronger than me.
