I think the cheaper ones are a great idea. I also think the expensive ones are ridiculous!

When you factor in house payments, insurance, construction materials and labor, maintenance, etc something like 25-30% of all economic activity goes to housing. Why are we spending so much money on shelter when everything should be getting cheaper as efficiencies and technology improve?

It's the same reason we have vast, sterile lawns that aren't used and drive 80k USD pickup trucks: status.
