It's realy sad to know that there are country's were childabuse isn't that big issue. Those childeren will never know how to treet theire own childeren because there is childabuse all arround them. So you have that famous visual circle.
But I think there is also another abuse. To give the child(ren) the material things they need, isn't enough. When parents deny childeren the love and attention they need, I think that's also an abuse. Childeren need love and attention.
I see a lot of people, even in my own village, who send their childeren out on the streets because mom or dad won't them have them arround. They have to enjoy themselfs. That's why childeren vandalize. They are bored. In my opinion you can hold their parents also guilty.
