There is a lot of comfort in knowing your house is paid off and if it hits the fan, you have s place to live instead of in a tent on a sidewalk.
Even a better feeling knowing that if something happens to you (assuming everyone reading this is the primary breadwinner/maintenance guy) that the wife, kids/grandkids have a place to retreat to if it hits the fan.

My opinion only but for those of us with Depression Era parents - we heard the stories and learned how to try and prevent them from affecting our families firsthand.
