Identify what they gain and what they give up when they make choices.
Students face many choices every day.
Identifying and systematically comparing alternatives enables people to make more informed decisions and to avoid unforeseen consequences of choices they or others make. Some students believe that they can have all the goods and services they want from their family or from the government because goods provided by family or by governments are free. But this view is mistaken. Resources have alternative uses, even if parents or governments own them. For example, if a city uses land to build a football stadium, the best alternative use of that land must be given up.
