What are the main causes of poverty?

The main causes of widespread poverty are:
(i) The low level of economic development under the British colonial administration was one of the main causes of poverty. The policies of the colonial government ruined traditional handicrafts and discouraged the development of industries like textiles.
(ii) High growth rate of population also contributed towards rise in poverty levels. It made the growth rate of per capita income very low.
(iii) With the growth in irrigation and the Green Revolution, many job opportunities were created in the agricultural sector. But the effects were limited to some parts of India.
(iv) Unable to find proper jobs in cities, many people started working as rickshaw pullers, vendors, construction workers, domestic servants, etc. with irregular and small income. These people lived in slums on the outskirts of the cities.
