I think companies could build refrigerators like this if they wanted to. And by wanted to, I mean if it would make economic sense for them. What makes economic sense for companies is to make the cheapest thing they can sell. If you think about that last sentence, what they can sell is not "what customers want". And therein lies the problem and the question. Why is it that those two things are not equivalent? The ratio of things that are what I want to buy compared to what I buy is surprisingly low. That ratio is probably highest at Ikea. I use Amazon a lot and searching for "things as I want them" is surprisingly hard. I often search for something then try to find the best lowest price ones that have the highest ratings. Like which refrigerator has the most stars and the most reviews at the lowest price. Amazon does not want you to shop that way, because it would affect their bottom line. (thanks a lot amazon!). So my take is that how we shop determines what companies can sell and that - in turn - determines what kind of things we can buy. The stupidest example of the problem that I can think of is a dish rack for washing dishes. The number of really bad/over priced products is enormous at both Amazon and IRL Walmart. One day (out of many) Walmart actually had a FUNCTIONAL REASONABLY PRICED DISH RACK. I bought it. Best dish rack ever. Best price (and yes it did come with a drain tray and eating utensil holder). In my opinion it is stupid that it is so hard to find and pay a reasonable price for a simple functional item.
