The meta argument I am trying to make is that recent arguments about this have shifted to including accounting for jobs (and usually experience levels), since jecjec was claiming that it's still the antiquated version that does not account for any of those things. If you want to have a discussion about the quality of any of those articles or the studies they're based on, well, that's a different discussion entirely, I present these as evidence that the discussion has moved, not that any of them are correct.
