"The growth has been attributed to the hard work of the labor force. External factors include the enormous economic and technical assistance provided by foreign countries, particularly Japan (see: Treaty on Basic Relations Between Japan and the Republic of Korea) and the United States, access to Western and Japanese markets, and the acquisition of foreign currency by Korean migrant workers in the early stages of economic growth."
other east asian countries look similar. foreign investments and international trade play a large role in a countries economic development.
that doesn't look like continued exploitation that was and still is happening in africa.
sure, the countries need to do their part to develop on their own. but we can also contribute by actually trading fairly with them.
