There are different kinds of value: to a hungry man it's irrelevant whether a bowl of rice is a wooden bowl or a golden bowl in fact the bowl is largely irrelevant altogether as long as he can get the rice to his mouth without spilling any on the ground.
If you mend a broken chair you are adding value to it; if you cover the broken chair in gold leaf you are not.
Maybe I'm talking about a hierarchy of values. A warm overcoat from the charity shop for a quid is at the top and a flimsy feminine haute couture item for £2000 is at the bottom.
