Yep. The $200, 000 probably is for a lot more than just clothes, a roof, food-I'm sure it includes lots of goodies. And people feel guilty if they can't give their kids what they had, or what other kids have.
It takes some creative bookkeeping to come up with that high a figure. Probably what is ebing looked at is how much people CHOOSE to expend on two children and then extrapolate on the cost of six. The "cheaper-by-the -dozen" families I have know say the expense tends to flatten out after four kids.
