It’s hard, yeah, to pick a tech baseline.  Farm with poking a stick into the ground to plant a seed, horse and ox, steam engine, gas tractor, on and on.  Where do we stop the specialization?  

As I remind my wife when she accurately notes that the resources in the world aren’t distributed particularly equally, if you think it is unequal today, how much more unequal was it 100 and 1000 years ago?  Technology has done a lot to improve physical living conditions, but we are still working on adapting our culture to take advantage of that.  Sugar, stress from constant interruptions, lack of exercise, etc.  As an ‘elder Millennial’ I remember a time when you set up a time to meet the day before, and if you got there and there and the other person didn’t, you just waited patiently for a while instead of the instant text and phone call and checking of email and markets and weather. Ah, the bliss of unstructured time.
