I'll admit I assumed you were screwing with the data (particularly as your original number was, by your own admission, wrong), but even with this correction, you're
still wrong. Here's your original statement;
People not in the labor force have not, as a group, "given up looking for jobs and instead prefer their leisure time".

The labor force is the employed plus the unemployed. Which means the remainder is
everyone who is neither. This includes the sick or disabled, it includes students, it includes people living off savings/inheritance, they may be retired early (if you're still looking at 25-54), they may be homemakers,
And y'know, BLS
asked them. We don't even have to guess; we have the data;
https://www.bls.gov/opub/btn/volume-...ey-working.htm
Of the 11.5% of the male 25-54 population that aren't in the labor force;
6% are sick or disabled,
1.1% are retired
1.2% are homemakers/caretakers
1.6% are going to school,
and just 1.6% cited "other reasons", which is a catchall group that includes "I've given up". So even that 1.6% is
too high.
So there's your number. Something south of 1.6% of men aged 25-54 aren't working because they've given up looking.
Not 20%,
not 11%.
Also, the single biggest growth in those reasons was
going to school. Between 2004 and 2014, the proportion of the "other reasons" category only shifted from 1.3% to 1.6%.
