You have too many kids on the government dime, you have demonstrated yourself to be a parent incapable of modeling a self-sufficient functional adult life, and all your kids will be placed in homes where they can learn that modeling.
I'm not saying that I am ok with people having more kids and mooching off the government.
But, there are not nearly enough homes for abused/neglected children as is.
Some parents may not care if their children are taken away from them, but I have worked with some parents who lost their parental rights to their children. Some of them were screwed over by the system. Others it was their own fault for not making changes. But I can say that those I worked with were all devastated by the loss of their rights, even when they could admit that it was better for their child to remain in their foster home or soon-to-be adoptive home.
Yes, there are people that just mooch off the government, but the system is not exactly designed well to prevent this. For example, imagine you are a single parent with only a high school diploma. The only job you can probably find is a minimum wage job with the take home pay of probably $1200/month (@40 hrs/week) give or take a few hundred. That money wouldn't probably even pay for childcare, not to mention rent, groceries, utilities, diapers (if they are young). Or maybe you live in a rural area with few opportunities for work and you can't afford to move your family or even buy a car.
Of course people should consider their financial situation before deciding to have children, but that doesn't always happen.
I'm just saying that we shouldn't pretend to know how these people feel about their situations unless we have truly known what it is like to be low-income (and I'm not talking about being a broke college student. That's different).
It is just unfortunate that we hear so many stories of people who leech off the government like octomom and not enough stories of people who have used the assistance to put their family in a better position.
