It's an interesting article.
I'm from Belgium, one of the highest house owners countries. Even though it's true it's a life-long debt and it might be risky (in case of crisis), housing is still considered as a Long Term Investment so that you can pass that investment to your children (after heavy tax deduction :)). I find interesting the article does not mention who actually owns all these houses and who benefits in the long term. After all, renting has a guaranteed zero ROI.<p>Also, recently, I've been looking at housing market in Munich and it's very very expensive. Renting is ~20% more expensive than in Brussels and acquisition is +100% more expensive. So, although I admit I do not know rest of Germany housing market, I have some troubles thinking why Munich would be more expensive than Brussels. And I certainly miss, from that perspective, why German system would be more interesting.
