They can.. if one of the following is true:

1. Their parents are doing exceptionally bad job 2. Their parents are doing exceptionally good job

Sadly, there is no way to tell, because not all kids are created equal. I know my parents had to basically remove our PC from our home ( how many parents have that option today? ) to put me and my siblings in line.

Unfortunately, this only adds to the problem, because bad parents tend to think they are great and vice-versa.
