It's actually the same thing just on a smaller scale (apart from the fact that people in France are rarely "obsessed" about work at all) - the jobs people don't want to work are the, relatively speaking, shitty ones. Nobody wants to work weird hours at the airport with a long commute, or police emotional/drunk people at a stadium, or run around serving food for hours at a time for comparatively little pay. Those jobs are much better than the equivalents in the US, healthcare/time off/etc.-wise, but they're still shitty jobs compared to the rest of the job pool.
