It's not that simple though - if you read the article it talks about how 1: High paying jobs aren't really increasing in number but are becoming ever better paid and 2: Low paying jobs are exploding in number but not in wages paid. So part of the problem is that there aren't many mid level jobs that get people in and help them then increase. Tech doesn't really automate the stuff that's not super low level (like cleaning toilets, or mopping floors), and it doesn't do stuff at the high end (M&A banking, negotiating policy, writing code). But it eats a ton of stuff in the middle.
