I don’t know. That looks an awful lot like the insurance salesman taking an old lady to the cleaners. Can we really blame a housewife from the turn of the century not understanding compound interest or having a sense for just how much inflation would be in the next 30 years? It seems likely that the insurance salesman did, he made quite a nice profit for his company (and probably a fat commission to boot).
Heck, $50/month for 30 years is only $18,000. The insurance company was laughing all the way to the bank.
