"Cheap to employer does not mean cheap to society"
Perhaps, but it's difficult to quantify the overall cost-benefit of a cheap labor force, so I'd stay away from arguing either way without presenting numbers. On the one hand, a cheap labor force leads to cheaper goods/food; on the other hand, a cheap labor force means tax payers have to pay for health benefits, education, etc. Are savings more than the costs? If anyone has numbers that'd be great to know.
