I think one of the cause of poverty is lack of education because not all people can afford to go in school due to high tuitions, corrupt government and the highest number of people here in our country. Government should give a permanent work to all workers and free education to lessen poverty.
Then what is the major cause for the lack of education? IMO, the root cause for disadvantages such as lack of education, poverty, corruption.etc is the rapid population growth. The population explosion results in increased competition for resources, and this in turn leads to poverty and corruption.
