english: Well no, because if you think about it, if Oz makes two spears and Adam make two axes, and then they trade, then they will each have saved an hour of work.
non_english: Teda, nie celkom, pretože keď porozmýšľate, ak Oz vyrobí 2 šípy a Adam 2 sekery a potom urobia obchod, obaja z nich ušetria hodinu práce.
