This guy rocks! He's gone to the bottom of bullshitization of the economy and showed that the finance industry has primarily "sourced" the proliferation of bullshit jobs at such an insane scale.
As he describes, the finance industry creates debt and then moves it around in elaborate schemes extracting money with each transaction. A part of this extracted value is then distributed through a feudal type of corporate hierarchy, based on political rather than economical considerations. He is saying that corporations now earn more money on this than on real production as most of them have a finance arm.
So now, based on his research, a big part (at least about 50%) of corporate job places are a part of the classic medieval feudalism, in corporate clothes. The author concludes that this is no longer a capitalism, and that this model is a dead end for humanity and needs to change. He suggests that everyone can work for fewer hours now while doing more meaningful job and have more of free time as a result of the change that is long overdue.
