Feeling the squeeze?

it's interesting to note that not all countries are feeling the squeeze.

I have a personal theory that countries with the highest rates of home ownership (read UK, Ireland, the US and Spain) are subject to wilder 'boom and bust' fluctuations than those with a higher level of social or strictly-controlled, private-rented accomodation. I can see how the mechanisms might work - but haven't yet found a convincing way to express them.
