Posts like that are sad, but I don't think I would even reply. The answers are all obvious, he just wants a short cut. Get rid of the three vehicles, cut the spending, and pay off the debt. Doesn't much matter how he goes about doing that, because in the end I don't think he will or even wants to. He just wants to complain about how he has a "spending problem", and then keep spending because hey, it's a problem, but not spending is too hard...
I would guess he will eventually not have the credit to spend, and then he will learn how to live on less.
Edit: I guess that's a bit cynical, maybe he will take advice, but he didn't even list his income or anything he had thought of to help his "problem", just sounds like whining to me, but who knows.
