Which is a least developed nation according to the imf?

I think the answer is Ethiopia.  It is reliant on agriculture plus poverty is everywhere.  Many people are still having a hard time in terms of food and shelter.  There are also those who die as a result.  Though recently it has improved its economy through foreign investments, it is still poor.

The unfree labors were able to improve the economy of the American society. These unfree laborers were the one manning farms and help in mass production. During this time when the US was concentrating on the agricultural sector, many landowners hired unfree labors. Many landowners would hire them because they have cheap labor and they can work longer than expected working hours.
