This scenario will never happen so I just don't think it is worth including.

Just imagine that these 45% of the population mentioned in this Oxford report really get unemployed after 20 years. When the people will start understanding what really is happening (i.e. governments around the world and its brainwashing will be unable to maintain "Luddite fallacy" myth) they will start so massive riots that never happened in the human history. These unemployed will clearly understand that they have nothing to lose therefore will fight to death. Also large part of police forces in many countries no doubt will support rioters (traffic and street cameras connected to image recognition software, drones already replacing many cops, so they also must fear about it).

As the result, some countries will turn to the non-capitalist economies, however other part will deepen into the full collapse and chaos. Even if you are strongly right-leaning, I don't think you will be happy to live in the country like Somalia.
