Well their comment was actually interesting, had you read it.

It's one of the only ones so far, mentioning the fact of discussing with the 18 yo son, trying to find the cause(s) of his behavior.

Most of the other answers are as stupid a "blablabla when I was 18 I had a fulltime job", good for you Jake, it made you into the pretentious adult applying one solution to everyone else problems and even worse giving those advice randomly to people on in the internet.
