Chapter 4 - Small Differences and Critical Junctures

This chapter is basically about even a small factor can bring in a big consequence into a country. An example of this will be about plague, called Black Death, which occurred in 1346. The plague spreaded from the Black Sea and then to rats then to many other countries. When it reached a country, it took almost half of the population. It made the countries to collapse, and face economic crisis. Since there are not many people to work, the range to career decreased, and the minimum wage declined as well, while the work hour increased. It eventually made the people in each country to suffer hardships. Any small matter can become a serious problem to economy.
