I don't understand this line of thinking. They started the show and they still had a private life but now that it has become more popular they are selling their private life for profit. If no one was watching the show, it wouldn't matter, the show would have been cancelled long ago.
I go back and forth on the privacy issue. I don't really think that they thought when it started it would become as popular as it has.
But then when I think about the cost of college for 8 kids almost all at the same time, holy cow that is a crazy amount of money. And unless you are very rich when you had the children there is no way most families could afford college for their kids.
So my opinion is that while they may have given up their privacy, they have secured their children's college education.
They seem to be trying in many different ways to add to their income to support their family.
Sure they have gotten perks like Kate's tummy tuck and Jon's hair transplant. I noticed earlier that some poster's complained about how a blue collar family could not afford the tummy tuck and hair transplant, and I agree. But a blue collar family could also not afford to send 8 children to college at the same time!!
