Some countries economy are constant and some economy rise and fall, from my understanding I suggest that is because of government,and population of the country. What is your suggestion
Yes, I agree with your thoughts. But I want to add one more thing that the economy can also be affected by nature. For example, in Dubai, it is a very small country and a very small population, but it owns one of the largest oil fields in the world. Since then, Dubai has become very rich. otherwise, it is due to natural disasters or epidemics and need not for example, you also understand how big its impact is.
