Seems like efficiency means (mostly):

- machines replacing people

So if I am not far wrong in connecting machine with efficiency and more machines = less people needed sometime after installation or immediately, then I just don't know how people are to survive / do jobs they like. And continue doing them... just growth is like a snkae shedding skin and getting left behind.

Seems like this way is doomed if we rely on 'job' and just not workable for people to survive unless there are enough supermarket and restaurants to give people enough dishes to wash
[oops dish washer]
