The current job system is based on the idea that jobs redistribute wealth: capitalists made profits, the profit was distributed when workers got paid, and the workers again helped the capitalists to amass wealth. So it was like rain: the profits rose to the top, but then they came down like rain in the form of wages.
This is now no longer the case in the same way as it was before. It is very possible now for people to make very large sums of money without employing anybody, either by buying whole companies in leveraged buy-outs and piecing them out like a butchered cow, or by having factories that employ very, very few people.
One of the really frightful aspects of this situation is that we have something like a third of the population working at an utterly insane pace, and on the other side, close to half of the population is obviously underemployed. It’s crazy.
