> The Labor Force Participation Rate is defined by the Current Population Survey (CPS) as “the number of people in the labor force as a percentage of the civilian noninstitutional population […] the participation rate is the percentage of the population that is either working or actively looking for work.”
No desire today != no desire tomorrow. A lower participation rate might indicate untapped potential or barriers to employment, such as lack of childcare or training opportunities.
How healthy would the economy be if 100% had no desire to work? That depends on why those people don't want to work and the overall situation, but until all of our needs are served by robots in reality likely not so healthy.
Participation rate is much more meaningful IMO
Example, the participation rate is currently ~67%, so its inverse is 33%.
This means that 33% of the working age population are currently not employed
