Well that's interesting. That seems like a pretty sound argument - we want less consumer spending, except on housing where we want more, so you need to offset the impact of rate hikes in just that sector. Or maybe we could try an alternate way to cool the economy, besides interest rates? It'd be risky though.
I still wonder why we have this problem in the first place. It sounds like our construction industry is unproductive for it's size but I can't fathom why.
