What the dependency perspective fails to recognize is that nation-states,however weak politically and poor economically, can take domestic steps to reduce their vulnerability to the vagaries and uncertainties of the international economy: if a country's foreign exchange comes largely from a single export commodity, making it vulnerable to price fluctuations on the world market, that country has the option to work to diversify its exports; if it is too dependent on foreign savings to balance its accounts or to undertake needed investment, it can take measures to steadily prop up domestic savings. Granted, these steps are fraught with difficulty, take time, and are more easily spelled our than accomplished. However, the larger point remains that developing nations enjoy some autonomy of maneuver, and that, to an important extent, their vulnerability to developments in the world economy is a function of their own domestic economic and social policies.
