Yes, good point, life insurance would be to put me back in the same situation I was before I died, i.e. alive!
I took out life assurance when I took out a mortgage. It wasn't a stipulation of the lender, but I thought it would be a bit rough if something did happen to me, and my parents were left without their younger son
and with a heap of mortgage to pay off, or alternatively to have to go and sort through all my stuff before the bank auctioned the flat.
When I was taking out the policy they had to increase the amount I am "assured" for, because when they put my details into the computer the monthly payment came out as less than their system allowed! I got a policy with no cashing-in value, thought that would defeat the object and possibly offer temptation later on. I don't mean for a gold-digging wife, I mean in case I decide "I feel pretty healthy, I'll cash it in and buy a car."
Getting this kind of stuff sucks, but too few people bother. I think you would have to be mad to be 35 years old with 3 kids and a dependent wife, possibly a mortgage, and not bother with assurance/will etc. As with all insurances it feels like money down the drain, if your uninsured car gets stolen, you have to walk to work. No biggy. If your family end up with no house, no money, no security, on the same day that they lose their husband/father, that is going to be a bad day for them.
