I try to not judge people and make decisions for what is right or wrong morally for others. I do think the state has a vested, legal and moral obligation to protect children. I'm watching Sister Wives and still debating how I feel about it. Nothing is always as it looks on the surface. So if things with them is worse than it appears, my goodness. It is really stressful.
I think that one reason the state is concerned with these large families is the financial obligation the state may bear if the father cannot do it, for whatever reason, (death, disability, refusal,etc.). The overhead for all of them is huge.
Last night as they looked at those 4 houses, I was trying to calculate how much money just the mortgages or rent would be, especially with only 2 adults working full time. What kind of money are they bringing in? You then have healthcare, utilites, food, clothes, cars, insurance, taxes, tags, etc. The cost to support all of them must be out of this world. They must be relying heavily on the income from the reality show.
