People get in habits.
They had a nice home, reasonable payment (in their eyes) and the 60k cars you mentioned. They're "getting by".
They decide now is the time to sell their current home for "more money than it's worth" and "invest" in a bigger home. Another excuse: Now is the time to borrow more money before rates increase.
Now they have those car payments and an even higher (longer term, too) mortgage. Stretched even thinner than before.
When SHTF, they don't have an emergency fund, savings, etc. Just more debt.
It'll get really ugly.
We could clean up on our home based on what we owe, what we paid for it and what it would sell for. But where are we gonna go w/o paying through the nose? Hell, I took my shop fund I've saved for for 15 years and invested most of it. I'm not building a shop in this current economic climate and overpay by 30-50%. I'll turn that overpayment into profit and build later.
