Have you seen the sacrifices made to afford those homes? Just because someone owns a home doesn't show the whole picture.
There are plenty of Americans that own homes and are struggling to make ends meet elsewhere.
Home ownership is set up to consume a person. Miss a payment and there are serious repercussions to one's financial well being, so it becomes a priority.
Up to a point, miss a credit card payment and it's extra fees. Miss a utility bill a month, and it's the same. Buy less food and you'll survive, albeit less comfortably.
