The story of the modern Western economy is that all the low-hanging fruit has been plucked from the tree of technological and productivity improvements (in the context of the regulatory environment).
Therefore, the proportion of profit and revenue rooted in exploiting human flaws is and will continue to rise.
Examples are:
* Humans engage with drama and negative content (ad supported media)
* Humans overindex on a sense of family/belonging/tribe (employers as family extract more work for less pay)
* Etc
Perhaps the biggest is regulatory capture and exploitation of regulatory loopholes.
