I'm just saying let's control the things we can control.
It is something we can control - but to your earlier sentence:
If kids had a mental problem like ADHD, parents didn't go to doctors like they do now. They disciplined them.
Right, so instead of seeking out help from medical professionals on determining if it is ADD or ADHD and getting a proper diagnosis, or discovering that the children are just not being raised properly - and giving those parents education on the subject and the proper tools to help deal with the issue, those parents should just discipline their children instead?
That seems entirely backward.
