I fear you are correct. 20 years ago a Haliburton frack crew had 60 guys working on it. They've streamlined and automated so much, they now only have about 20 guys working a crew. So now there are 40 guys who would have had a fantastically good paying job who are doing something else instead.

Jobs will never completely go away, but the good jobs will get fewer and fewer. Then what will we do? We can't all drive for Door Dash.
