Kathy, my opinion is very similar to yours. Too many people consider their children not people with their own preferences and wishes, but rather free caregivers and providers. And too few people want to have children because they want them to be happy and to enjoy their life. Perhaps everyone heard or read of, or had seen cases when people would giving their kids trouble for choosing a "wrong" partner, or "wrong" lifestyle and so on.
I see another problem: people who have kids just because they want to have someone small and helpless and depending on them, someone they can cuddle and pet. Goodness! Kids are people at the certain stage of development, not toys! But some people still see their grown children as babies needing constant care and supervision.
Of course it would be nice to see people being a lot more responsible in their decisions to give life to another person, but it probably not going to happen in any near future. I see solution only through education and changing attitude about child-free people.
Also, of course, agree that child abuse can take place in families with any level of income or social class. My own father was belonging to the intellectual elite of the country, which did not stop him from being an abusive parent. For some reason many think that the whoever has no money must have no children.
