Scott goes on to make the usual condemnatory noises about child labour and poverty in poor countries. That child labour is necessary in very poor countries to augment the family's low income is certainly a deplorable state of affairs. But to deny these children work is just phoney compassion that will only make their situation worse. The only cure for poverty and child labour is economic growth. The very thing the Greens are bitterly opposed to.
Growth is a process of capital accumulation.
This and only this can eliminate poverty. Only by raising per capita investment can we continue to raise real wages and hence living standards. It is the rise in living standards that eliminates the need for child labour. The Industrial Revolution heralded the process that made it possible for the first time in history to dispense with children as workers. Child labour was followed by the workers-rights argument.
