How did civil wars lead to economic problems?

Civil wars can lead to economic problems in a variety of ways. The destruction of infrastructure, disruption of trade, and displacement of people can all lead to economic hardship. Civil wars can also lead to a decrease in foreign investment, as investors may be wary of investing in a country that is in the midst of a civil war. Additionally, civil wars can lead to a decrease in government revenue, as taxes may not be collected and government services may be disrupted. Finally, civil wars can lead to an increase in government debt, as governments may need to borrow money to fund the war effort.
