[Fusilier]

Nevermind the slaver parties hunting people... that shit just gets you or your merchandise killed and uses up resources.

Most slavery today is based on bondage labor. You're taken on as a worker and promised an income - usually a ways from home. Then when money never comes you find out you also can't leave. The method works extremely well and with the hoards of hungry and desperate refugees roaming about, I see no real need to change tactics and go hunting people.

Edit - I see HQ touched on this already.
