The way it works, ideally, is there's competition & people vote with their dollars according to how they like the benefits & the prices.

If something is very beneficial, but in great supply the price tends to be low, like clean water in Sweden, it will be very cheap, so I don't think somethings price on the market is enough to decide how much benefit it has. Somethings which are of great benefit to us, like air we can breath, are even free.
