The most accurate response regarding how the resource curse has affected Saudi Arabia is:
Wealth from natural resources helps to support the autocratic government.
Saudi Arabia's vast oil wealth has led to the entrenchment of its autocratic regime, as the government has utilized that wealth to maintain social stability and suppress dissent, which can be a characteristic of the resource curse. While other statements may hold some truth in different contexts, the primary effect in Saudi Arabia has been the way its resource wealth has enabled the government's control and stability.
