<human>: A friend of mine is in a family of eighteen kids. Three are natural-born. Their parents adopt a baby or troubled child, and as soon as they look like they won't need direct adult supervision, the parents go and adopt another, ignoring all the rest of their kids. They have no steady job, and instead live off the welfare money and other sources (The mother "runs" an online advertising firm, and the father takes care of their backyard petting zoo. Yes, petting zoo.) I hate seeing this done to them. Two of the kids are college-age, and yet are forced to stay at home and take care of the other younger children. Only a couple go to public school, but they only go for a year or two at a time.
Every time I talk to the older ones over the phone, they avoid family topics. They sound uncomfortable whenever I ask how things are at home. What can I do to help them, if anything? It's may not be my business, but the oldest boy is one of the smartest people I know. He would love more than anything to go to college, he says.

Can you condense the text into three sentences or less?
<bot>: Crazy parents have a ton of kids and no jobs. Holding behind older kids' lives because of it. What can I do?
