Well they do but most aren't willing to even pay they high end prices so it's the cheap stuff that sells and what people want.
There is a theory about why average home sizes ballooned from an average 905 ft2 home in the 1950 to well over 2700 ft2 in the mid 2000s and often featured 2 storey great rooms that are actually horrible to sit in.
Builders claimed that customers would not buy homes that were not larger and didn't have great rooms, or whatever trend was the flavour of the day.
Detailed research however disproved the builder's claims. Consumers would have preferred smaller, better designed, better built and more luxurious homes. Sarah Susanka pitched a philosophy based on this fallacy of the fallacy of what builder's claimed consumers wanted. The not so big house became a minor movement in the custom home market.
So I always challenge what people say consumers really want, and ask are people forced to buy what manufacturers force us to buy... and does China have a policy to sell cheap consumer goods or is that end result just a natural evolution resulting from the Chinese system?
