When a person buys a home with a mortgage (congrats, by the way!), they gain the possibility of getting some return on the money they spend to have a place to live. It might work out long-term or it might not, but there's a chance (and it's often a pretty favorable one) that it works out well-enough as the years tick by that the light at the end of the tunnel keeps getting actually-closer.

Every day, thousands of folks do emerge from that tunnel and gain the ability to make profound statements like "Well, at least the house is paid for."

This is in stark contrast to renting, wherein: There is absolute certainty that none of the money spent towards having a place to live will ever be returned. It doesn't matter how much is spent: Whether a little, a lot, or a lot more, that money is always just unilaterally gone. There's no chance at all of anything else happening. The odds of winning are nonexistent. There is no light at the end of the tunnel, and there never can be -- it's just inescapable darkness in there.
