I'm not going to go into all this stuff about Holland because I don't know a massive amount about it and it's rather late in the evening where I am right now, but I will say this here is hair-splitting. Secondly, I'll also say that a given profession being legal doesn't mean you can afford to be slack about being forced into that profession illegally. There's always ways to break up criminal gangs, and police can take them down for essentially importing slaves regardless of whether the job their being forced to do is legal or not.
