First, it's your opinion they children are being expoited. We have no idea if these kids now have healthy bank accounts, and K & J are not the only ones to be paid. If the kids are earning money and loving the attention, they may not agree with you, when they grow up and have their own funds.
Second (not that I ever did) but as a person from the 60's, if they take away all the children of parents that smoked something other than cigarettes, where would they put all the kids?
I'm still so flabergasted that so many think she is a horrible person. I just can't figure out what it is she did that makes her that. Snips at your husband, who also snips back? Wears a bikini? Spanks her child? Has a funky hairdo? Says ummm when she speaks? Doesn't respond to fans in the street? Takes out only a child or two at a time? What about all the nice things she does (and there are plenty of those). What about the fact she loves her children? Heck, nowadays, you don't lose your kids even if you live unmarried with someone, while you are married, or if you have an affair, as long as the kids are well taken care of.
