Something something "why don't you do this Ukranians, but to Africans/Arabs/Middle Easterners/Latin Americans". FWIW, the US goes the closest to this route in terms of partial imprisonment, and people still *try* to come here in the hopes that they'll find work because earning first world money is better than nothing. And nobody wants the optics of dead people in the sea in sunken ships or coated in blood at the frontiers.
