This sounds like an oxymoron.
Financial efficiency and value often appear to be at odds. Amazon certainly appear to spend less resources in the delivery of goods. Low cost of acquisition isn't necessarily correlated with greater value in terms of human fulfilment.
I've often wondered why we don't have [more/widespread] community kitchens, less work needed for food production, reduced waste and transportation costs, etc.. Why can't I go somewhere and get a quality, healthy meal that is cheaper than what I can make at home.
