You're putting words in my mouth, I never said it was some sort of social step down or any such nonsense. I merely described it as downskilling. Now you can be semantic about it and say that learning any new skill is a form of upskilling. Fine. But the point is that there is a very limited scope for additional skill development. Once you've learned how to crimp a fitting onto a pipe you're done (I'm over simplifying but you get the gist). On the other hand once you decide to go into a technically complex field there is neverending scope to continue building in your skills.

It's like choosing to learn checkers over chess. They are both fine games, it's just that there's more scope for growth in chess than checkers and only a fool would argue otherwise.
