Buying and selling?

Persons who are buying and selling are involved in the market transaction and are in fact assessing the condition and making a decision, and they're doing it in roles which make them essentially anti-social - make them concerned only with their own well being because it's the only thing that they can be concerned with because it's the only thing they have knowledge of. The only thing they can assess is whether or not they like the price and whether or not they like the product.
