Yes i reside in a less populous area (south France) where you can be happy to find a job at all, if that's what you're looking for in life. But from my understanding of bigger agglomerations: there's a high turnover rate in precarious jobs, but just because you can afford to find another precarious job elsewhere doesn't mean you get the privilege to choose where precisely. I hear in suburbs of capitals like Berlin or Paris it's not uncommon for people to travel 2-4h daily to work and back. Chances are if you switch jobs, you might have the same travel times, but to a different location.
