Today, trade is merely a subset within a complex system of companies which try to maximize their profits by offering products and services to the market (which consists both of individuals and other companies) at the lowest production cost.
Tänapäeval on kaubandus ainult üks osa kompleksest süsteemist, mis püüab maksimeerida oma kasumit, pakkudes tooteid ja teenuseid turule (mis koosneb nii üksikisikutest kui ka muudest ettevõtetest) madalaima tootmiskuluga.
