I wouldn't, certainly not to the degree they have taken advantage of their children.
Bottom line it's not my children's responsibility to house me, clothe me, feed me, and financially support me. Child actors now have very specific laws that protect them from becoming the workhorse that supports their parents lavish lifestyle and then when they grow up there is little left for *them*, that *they* earned.
Children on reality t.v. shows have no such protection. Which means their parents are free to take every dime earned from that show and spend it on whatever they want (like million dollar homes). And what happens when the sextuplets are old enough that they're no longer "interesting" t.v. any more and the show is canceled? What happens when the book deals and the speaking engagements slow down? When you are spending money at the clip they are, then you are literally depending on your fame as the parents of sextuplets to support you. Property taxes in PA aren't cheap, what is the fallback to sustain their lifestyle when they can't get it off the backs of their children's fame? How much of their children's right to privacy been stripped for their parents right to be opportunistic and make money?
There are many, MANY families of higher order multiples who choose to protect their children's right to some semblance of privacy and a normal life versus hawking them out to every Tom, Dick, and Harry that's willing to pay a buck. The septuplet family that has lead a low profile. There is a family in the U.K. with Octuplets. There are NUMEROUS families of sextuplets and quints that don't sell their children out to the media. I know a family with the only set of quintuplets in our state, who also have three other children. They have 8 just like J&K and their quints are 4 year old. Mom stays at home and Dad works and they scrape by.
There are some things in life worth a lot more than money. Integrity is certainly one. I can see have a television special here and there, and accepting offers for trips or things that you otherwise could not have afforded to give *TO YOUR CHILDREN*. But when it becomes a way of supporting *YOURSELF AND YOUR SPOUSE*, and affording things for *YOURSELF* that you couldn't otherwise get if you didn't sell out your children then I'm sorry, I see very little integrity in that.
Just one mom's humble opinion.
