Globalised world makes services and goods cheap but at what price ? I see people and countries wanting self sufficiency and heavily taxing or even banning mega corps. If production of goods will be so cheap that it will make 90% of workforce obsolete that will effectively leave countries at the mercy of mega corps that can afford r&d and servicing the automation machinery. People are already fed up with eating meat that has been transported from the other part of the globe or just buying nails or some other basic commodity items that could have been produced locally.
