The fact that there's a lot of real jobs making iPhones just means there's a lot of BS jobs that will hang onto them.

Of course it's true, you need a LOT of specialists to make iPhones.

I would also wager that a lot of real jobs are lost because there's a tradeoff between gunning for such a job and just settling for a moocher job. Some of those real jobs would consist of automating away the assembly line jobs. It's just that we don't have that society yet, so the manager who doesn't know how to do the automation hires miners and assembly workers, who are obliged to do something in order to make a living.
