You are not disproving his claims, 35% of the households being homeowners means absolutely nothing without knowing how many live as rentees for example. Also am I an houseowner if I paid 90% of the mortgage? 'Massive numbers' can mean anything between 0.01% and 99.8% depending on where you live, who are your friends and coworkers etc.

All that being said, it sounds just like any other western country, or in fact any country in the world apart from very, very few. Welcome to 21st century, you have mostly FED to thank for this, everything else just snowballed in its bad decisions.
