Want to find out why so many kids turn out bad? Become a secondary school counselor or administrator.
A couple of years ago, we had problems with a girl who constantly causing trouble. Her mom (a single parent) always thought we were mistaken, or that we hated her. Girl finally did something that got her sent to juvenile detention.
Mom lawyered up and got her kid released on probation. During which time she participated in an armed robbery that got her sent to prison. She was 17 and sentenced as an adult. Second day in prison, she mouthed off to someone and got beaten up. Mom didn't know until she went for a visit a few weeks later.
We know this because mom came up and told us. She blamed it on the schools for sending her kid to juvenile detention, which "made her a criminal."

If you discipline your kids appropriately, God bless you. Not enough parents do.
