Business experiences. I would point out I labeled them opinions, but they would match the business experiences I've seen. Getting a true survey would be difficult. It is also quite unlikely that all cultures have the same preferences on the price/quality tradeoffs, and Americans are pretty heavily loaded on the "price" side. (I believe Wal-Mart is having some success overseas, but they had explosive growth in the US for a reason, and I'm talking pre-recession.)
