You, dear, don't know me from Adam, so don't preach to me. I sympathise with your problem. Really. But don't try to give me some snow job about how the legions of ill-behaved, undisciplined brats running amok in otherwise polite society are all the victims of some legitimate medical problem. They aren't, and you know it. In some cases, I'm talking about members of my own family; I know precisely what is, and what isn't going on.
As for my own (mis)behaviour? I certainly did not run around restaurants screaming as loud as possible. Nor did I exhibit such behaviour in department stores, groceries, etc. I did not openly defy my parents in their face and to their despite, and expect to get away with it. The few times I tried it, I quickly learnt the folly of such ways. Likewise whining, begging, crying, and throwing tantrums. The few children with legitimate medical problems, who literally can't control themselves, are neither excuse nor explanation for the legions of spoiled brats whose parents are too lazy, stupid, or self-centred to properly teach them.

You just seem to have a lot of anger towards kids. Even the wildest of kids has good qualities. I think we need to help parents to help these wild kids. Parents have a lot of pressures these days. Two parents may need to work to afford a place to live. Grandparents and other family members live faraway.
There is also an increase in the number of disabled kids. 30 years ago, premature infants didn't live. Now you have infants as young as 24 weeks surviving. Unfortunately, they have lots of special needs. Also, there are lots more children of women that used drugs while they were pregnant. These children also have lots of special needs. I truly wish we can find ways to help these children.
Also, even the best of kids can have a bad day. Just remember even our own dear President had a wild youth. I think he's turned out okay.
