Since I don't identify with the concept of leaving an estate to heirs, I guess I'm wondering why he doesn't simply do nothing. No insurance, no pre-inheritance. If he (and his heirs) are lucky, he'll live a long, healthy life and then leave a little or a lot to the heirs. If he has to go to a facility, he will self pay until the money runs out and then go on Medicade. No scam, no fuss, no muss. Only real downside is there is a chance the heirs might receive nothing. I'm taking a wild guess that they are just fine with that. I would be (and was with my parents who came out even).
Just my 2 cents worth. YMMV
