Economic research

The origin of economics study is to study how to make nations wealthier and greater. It was more about designing a model to allow nations to grow stronger. One of the examples of such economists is Adam Smith. Afterwards, economics study turned to look for ways to solve some real world problems. Modern days, economics study has been diversified that some try to find out the causes of some economic phenomenon, some try to develop solutions to solve some current economic problems. However, most of the economists do not try to build up a new economic system that replaces our current system. I think that the cause of this is because of Karl Marx. Karl Marx did set up a new system that actually partially contributed to the chaos of the Cold War. Nowadays, no one believe that a systematic change can lead to a perfect world, which shows now people become more rational and less optimistic.
