rich seems to be getting richer, and the poor poorer

There can be a problem that the rich seems to be getting richer, and the poor poorer. The companies that have a lot of capital and resource get more wealth, and otherwise, the small companies get less wealth. The competition of many companies is getting expanded. They compete not only in their own country but also in the all around the world. In this process, each company tries to enhance its competitiveness in the world market in order to survive in fierce compete. However, only a few companies survive and grow to big capital, finally they come to dominate the world markets. On the other hands, the rest of the companies are destroyed and go bankrupt. Also there is the same problem to the people in the countries. Generally, people say the global economy is growing with the globalization, but the gap between the rich and the poor is ever widening than the past. For example, in the South Korea, the 2/3 of people formed the middle class and led the society in the past. However, in the age of globalization, only 20 percent of people take the lead the society, and rest of the people dropped under the level of poverty.
