> Some places like Canada even import developing world labor to work these jobs because they cant find local employers for the wages they offer.

This might be naive of me, but is it equally valid to say that these Canadian employers are only paying such low wages because they have access to cheap migrant labor from poorer countries who are willing to work for less pay than local labor? Without access to their existing low-wage workforce, these employers would have to raise wages until they attracted enough local labor.
