The classic reply to that is if those jobs were still available, we'd have to give up all our post 1950s technology. You starve people enough, hunger drives some interesting responses. If keeping your iphone means watching your kid die, lots of people will totally go for some kind of neo-Amish 1950s revival. Or just go full on Amish. Currently the Amish standard of living is somewhat higher than the general population and that is only going to increase in the future as the median standard of living continues to decline with technological "progress" and environmental change, while the Amish hold relatively constant, which is going to drive lots of recruitment. If you give a choice of living under a bridge while starving in iphone-land or being a successful carpenter in Amish-land, well, kinda a no brainer choice there...
