For both gambling and insurance, the return is chance x payout. And both the lotto company and the insurance companies reap huge profits from the odds.
We try to keep our finance fairly separated, therefore neither would be in trouble if the other one perishes. My death wish is fairly simple. Dig a hole, throw the body in and let the worms eat it, so not much final costs. My asset should last the family for a while. Even if I bought a $100,000 insurance, it would not be all that significant. That's another reason I don't like house. It's just too illiquid and have too much fix costs associated whereas renting is a lot more flexible.
Car insurance is difference since the payout would be unlimited. My friends in the insurance companies said they usually hate car insurance since it's impossible to predict the damages. A client hit a bridge once and they lost millions on that one.
