I think the majority of technologic trends since at least 2000 have been fundamentally deflationary in nature, for all material goods. We simply are conserving more; using less materials and energy for the same set of consumer uses. Unlike the last industrial revolution where new energy hungry appliances were being invented and new ways of life expanding, most new inventions today are long lasting, low energy consuming, or are just innovations making existing products cheaper.

That central banks and treasuries insist on inflation above zero when we should probably be deflating and letting technology make everyone wealthier...no wonder there are property bubbles. (Note this inflation argument encompasses the effect of trade deficits in creating asset bubbles, because inflation/treasury debt breaks the trade/currency feedback loop)
