Not actually all that hard to understand: yes, lots of talented devs who hate wasting time have a job they like. However, N is a big number here, so your assert

Not actually all that hard to understand: yes, lots of talented devs who hate wasting time have a job they like. However, N is a big number here, so your assertion on that fails. Also, your assertion that "as job satisfaction declines, time opens up" also does not follow. Plenty of very talented people are both unsatisfied and snowed under with crap. Finally, saying that a Dev wouldn't be snowed under because they wouldn't be applying willy-nilly would hold iff hiring practices at firms where even remotely efficient and fair.
