Characteristics of U. S. economy
Rivalry: rivalry is when different stores compete to get the most customers. This is represented by this picture of Michigan and Michigan State football helmets because they have an intense rivalry.
Markets: places when free trade takes place. This picture of two girls trading lunches represents this because they are weighing what foods they want and making a trade that's good for both of them, in a market (lunch room).
Private Property Rights: the right to own and maintain your own private property. This picture represents that because it warns people that they are on private property, and not to trespass.
