Somebody has to care for them to want to enslave people to have these children cared for. Otherwise, they would be left to die. The fact that it's an issue shows they will be cared for. It's only a matter of expressing that compassion morally without tyranny. In the end, if violence has to occur, it's only due to laziness from the people who send the brutes to get the children cared for.
There are an estimated 30 million real, actual, no-foolin' slaves left in the world. By claiming that a billionaire who pays 15% tax on his capital gains is in the same league with them, and spending 99% of your time complaining about his "plight" while ignoring the real slaves, you pretty much make yourself out to be a disgusting piece of shit.
Your arrangement is just about percents? So, at what point does one become a slave? 50%, 75%, 95%, 99.999999999% ? what then?
