The discovery of oil comes with a huge blessings capable of transforming individual lives communities, states and even countries if well managed. But a situation where the proceeds are miss managed it will turn to be a cause as individual will rise against individual, states Wil rise against starts, countries will rise against countries.
There is no doubt about that, anything that is mismanaged can cause problems and be worthless or will be used for evil means. Natural resources, be it oil, gold, or anything else, are a blessing for any country where they are discovered as this can change the faith of the country and their people, but this is only possible if the leaders aren't greedy, corrupt, and unethical, because if that is the case, they are not going to use the resources for the betterment of the country and its people but they will use it only for personal benefits.
There are a lot of examples in the world regarding these things, a lot of countries that are rich in minerals and natural resources are developing at a great pace, whereas some countries where there are also a lot of natural resources found are still third-world countries because of their corrupt leaders.
