The economical policy of the U.S. military government in Korea was established within the boundaries of U.S.’s own policy regarding foreign economical situations that were aimed at establishing a global capitalistic system led by the U.S. itself in the post-Second World war world. Naturally, the U.S. military government intended Korean economy's absorbtion and integration into the global capitalistic system, and also into the U.S. economy’s range of control.
As a first step to establish a capitalism-based system inside Korea, private ownership and marketplace economy was introduced to the Korean people. The U.S. military government deliberately neglected the breakdown of Korean industries, in order to make room for American products being imported into the Korean market. They also introduced massive surplus products to Korea in the name of aid, which may have helped stabilizing the Korean society a bit, but without a doubt seriously damaged the Korean economy's independency and its ability of self-sustenance. As a result, the Korean society started to show some symptoms of chaotic disorder, and the U.S. military government feared that such disorder would lead to social ruptures or possibly a political upheaval. So they issued new orders and policies regarding certain economical factors such as food supply collection, restraints over acquiring daily necessities, efforts to control potential inflations, and maintaining stabilized price status. Yet most of them did not Drove very much effective in the end at all.
Such economical policies on the U.S. military government's part prevented the Koreans from developing a stable economy of their own, and made them more dependent on foreign aid and supplies. After the Liberation, many middle-sized corporations and companies were established but all failed to survive in the long run. Only the major corporations backed up by U.S. supporting assistances survived, and started to lead the Korean economy. And such economical environment staged the typicality of the 1950s’ Korean economy which couldn't survive without the U.S. economical aid.
