If he needs help, you should offer him a bed and some hot meals – Remember, no matter what, losing a job can be traumatic, so he will need your support. That does not mean “tough love” is not called for. **Just don’t give him any money**.
He may continue to spend what little he has on MLM products – its ok – It will eventually dry up and he will accelerate his path of discovering the truth for himself. The rest of it has already been covered ….
Make the MLM show its true colors. The bad guy will expose itself for what it is. Once the gravy train of PV/BV stops flowing into his upline’s coffers, YOU CAN BET they’ll flush him without a thought, saying to themselves (or screaming at their steering wheel): “Some Will! Some Won’t! So What!?” God! Just typing SWSWSW gives me the willys!
I think the best thing that could happen at this point is for him to show up on your doorstep. If rent is due on the 1st, he’ll see he has trouble then, but it may depend on how long his landlord takes before evictions on how soon he’ll show up. One interesting thought: I doubt he has many actual “possessions” that he took with him that he hasn’t sold off. If he’s actually evicted, they’ll take all his stuff and put it on the curbside. That would include those stacks and stacks of CDs.
I’d like to see how many of his “friends” help him if that happens. That’s when you can be sure he’ll be coming to you for help.
