The poor will always pay the price for the rich. Until they can't take it any more, organise (at last) and revolt. Which in history very rarely happens as the rich master the art of appeasement.

Until now the poor were useful (cheap labour, cheap brains), but will change in the future. A.I. + robotics hold the potential for an inverse revolution.

Unless the poor get there first (cooperatives), but that is highly unlikely. If all the poor taxi drivers of the world had pitched in, they today could easily have owned Uber. But they don't.
