i think the word "slave" is rude, i would better say them as a domestic helper. I am for the domestic helper who is above 13 or 14 but i am against below 10. I have seen domestic helper as young as 7, after seeing that i felt like i never did adult work like that when i was 7. I don't think all of them will end up in prostituion, they can also learn lots of creative things, like cooking which is common and sewing if we send them for its training...thats good idea to teach them any one of these things because one day they can also work by themselves.
