What's wrong with me offering a starving third world child the ability to be my full time house maid for $1 a day and room and board? Many of them would love the chance. Some will literally die from expose and lack of food and clean water. Yet it would be quite illegal for me to give them a chance to survive. I'm gone out the house 10 hours a day, sleep 8 hours, and have very few actual chores. They would only need to cook me a lunch to take to work, and do a little light cleaning. They could use the free time to jump online and learn from resources they would've never had access to. I'd even help them by getting them access to some skills appropriate help. There entire life would be massively improved, and once they feel ready to move back to their homeland and make their own living, I wouldn't stop them. Yet that isn't only illegal, if I tried to foster a child and treated them this way I would be considered a horrible human being. Weird, no? The main answer to this is that allowing this, while it may seem reasonable in a single case by case basis, caused massive social problems (child slavery lite) that justifies forbidding me from making an offer that could save the life of some child. The second and third order effects are too bad. (Or maybe they aren't and it would actually be better overall to allow it. It would be an interesting discussion either way.)
