The End Game of Capitalism + Technology

[T]he emerging global economy tends towards a state in which only 20% of the workforce can do all the necessary jobs, so that 80% of the people are basically irrelevant and of no use and potentially unemployed.

When this logic reaches its extreme, would it not be reasonable to bring it to its self-negation? Is not the system which makes 80% of the people irrelevant and of no use, itself irrelevant and of no use? The problem is thus not primarily that a new global proletariat is emerging, but a more radical one: billions of people are simply not needed and all the sweatshops cannot absorb them.

[S]hould we continue to play the humanitarian game of taking care of those left behind, or should we tackle the much more difficult task of changing the global system which leaves them left behind? Without such a change, our situation will be evermore irrational.
