Do they? Has doubling the work-force helped Western economies? I think that Elizabeth Warren & others have questioned that idea - i.e. that the wages were reduced to compensate for the increased labour supply - although even if not beneficial for individual families it could still be beneficial for the economy as a whole (and especially for the capitalist class).
