Mother Atkinson thought that every one should have a trade, or something to make a living out of , for rich people may grow poor, you know, and poor people have to work.... so when I saw how happy and independent those young ladies were, I wanted to have a trade, and then it wouldn't matter about money, though I like to have it well enough.

The exchange ratio, the price, is not the product of equality of valuation, but on the contrary, the product of a discrepancy in valuation.
