You say children are "free workers", but I would beg to differ. Sure, you can try to not feed them, but the production efficiency goes down dramatically, and some of them die (like the pussies they are). I personally would feed them plenty, but not too much to where they take it for granted. Secondly, you know how water-dependant younger workers are? Go***amn, just one goes through a whole water bottle in a day. Of course, being the great master I am, I give them half a bottle a day. But not only do they complain, but some STILL die. Dont even get me started on the whole complaining part. All day, they whine whine whine. I let them sleep a generously two hours, but they still pretend their tired. Thats why I'm replacing all of my children with femboys.
