I don't quite see your point. I agree that both traditional and modern slavery is not voluntary. But if there are no other options, other than taking an extremely low-paying job, then modern slavery is exactly what you get.

None of that contradicts what I originally said. Not having a minimum salary, and removing options for people to get by when they find themselves unemployed, creates a perfect environment for modern slavery. The OP that I replied to above seemed to think this is a good idea - it is obviously not.
