I am puzzled by the references to slavery. The people smugglers are not slavers, as the refugees pay to be smuggled, or indenture themselves.
Not supporting them, you understand, they are arseholes who deserve whatever happens to them, but they are not slavers. The morality of the smugglers is similar to slavers, but my pedantry prevails.
Indenture has been a means of affording transportation to many 'rich' countries, and the race of the indentured has nothing to do with it, as descendents of many German-Americans settlers can attest.
