In terms of natural resources, social institutions, and economic governance, each country has different rates of influence. There are 196 countries in the world. 25 of them are very rich, with a per capita income of over $ 100,000 per year. Most of the rest are relatively poor countries and some are very, very poor. All countries more or less are on the road of development. But in poor countries, this is extremely slow. Remarkably, poverty and corruption are correlated and directly influenced. The richest countries in the world are also the least corrupt countries, and the most corrupt countries are also the poorest countries. When corrupt states, they can not collect enough taxes to build one body. Natural resources such as oil, precious metals can be a real problem. Poor countries tend to view them as a trump card. These natural resources are called "amplification effects" by economists. They will help a country with a wealthier institution, but with a bad institution, it will even make it poorer. This is called "resource traps".
