How do I explain why debt on debt is bad to my brother?
The only thing that comes to mind is a recent HBO Real Sports segment (http://www.youtube.com/watch?v=WDjkbgrgcmo) on a couple of NFL players who blew all of their money.  Seeing how they've ended up might make the right impression, but given that your brother ran up $148K in debt, I'm not optimistic.
