In the context of trade and immigration, borders are often discussed as a means of excluding foreign workers and foreign goods. In one way of thinking, borders provide an opportunity for states to exclude private actors such as workers, merchants, and entrepreneurs. On the other hand, borders can also serve a far more endearing function, and this is found in the fact that borders represent the limits of a state’s power. That is, while borders may exclude goods and people, a state’s borders also often exclude other states.
For example, East Germany’s border with West Germany represented the limits of the East German police state, beyond which the power of the Stasi to kidnap, torture, and imprison peaceful people was far more limited than it was within its native jurisdiction. The West German border acted to contain the East German state.
