Many economists believe that the key to breaking the vicious circle of poverty is to

A) cut down the mortality rates in poor nations.
B) reduce the birth rates in poor nations.
C) increase the mobility of labor and migration.
D) increase the rate of capital accumulation in poor nations.

Increasing the rate of capital accumulation in poor nations can create more jobs and opportunities, leading to economic growth and development. This can help break the vicious cycle of poverty by creating a more stable economic environment and increasing access to education, healthcare, and other resources. Additionally, it can reduce the reliance on foreign aid and encourage investment from other countries. Cutting down mortality rates and reducing birth rates may also have positive effects on poverty reduction, but they may not be sufficient on their own. Increasing mobility of labor and migration may be beneficial in some cases, but can also have negative consequences such as brain drain and social disruption.
