Mark Warshawsky of George Mason University's Mercatus Center was on Econtalk and had the same theory and numbers to back it: http://www.econtalk.org/archives/2017/01/mark_warshawsky.htm...

Edit: also interesting point Mark Andreesen made: we don't have too much automation, we have too little at least in some sectors. If things keep going as they are now, a TV will cost $10 and health insurance and college $1,000,000.
