But don't worry, you will be at moderate risk of the car breaking down before 10,000 miles and you can't fix the part because it has been deliberately engineered so that mechanics can't fix it and it has to be replaced.

I did some jank estimates and I think the 50 year mortgage thing would stave off the affordability crisis for about 10 years before we're back to where we are now. Then back to the normal increasingly unaffordable housing. Then a total meltdown of material conditions when those loans start getting past 30 years and people become too old/sick to finish paying off their mortgages.
