I have also heard that human trafficking increases after legalisation. This makes sense to me since other relatively unpleasant jobs are also done by illegal immigrants in many countries.

My remaining question is how we draw the line between voluntary illegal immigration and human trafficking for this class of work. I'd guess from my perspective even the voluntary immigration would seem beyond harrowing and carries risk of abuse and death along the way, so it would be easy to paint all of it as bad, yet clearly many think this is the best chance for them and their families.
