Why every society has to choose

Scarcity is the starting point of the whole course. Land, labor, capital and entrepreneurship exist in limited amounts, while the things people would like to have keep growing. Because the resources can never stretch far enough to cover every want, every individual and every society has to pick which goods and services to make and which to go without. Choice B states exactly that: limited resources cannot meet unlimited wants. Even a perfectly efficient, perfectly equal economy would still face scarcity, so it would still have to choose.

Each choice

• A. This flips the logic. Efficient allocation helps a society get more out of what it has, but no allocation can satisfy wants that have no limit. Choices are forced by scarcity, not by a promise that efficiency will fix it.
• B (correct). Scarcity is the reason any choice exists: if resources covered every want, nobody would have to give anything up.
• C. Whoever picks this is thinking about the tradeoff between efficiency and equity. That tradeoff is a real topic, but it is not why choices exist in the first place, and efficiency does not automatically make distribution less fair.
• D. Unequal income affects who gets the goods, which is a distribution question. A society with perfectly equal incomes would still have too few resources for all wants, so this cannot be the underlying reason.
• E. This borrows a trade idea. Whether a country has comparative advantage in everything is about specialization, and in any case the statement does not explain why any one person or society has to choose.
