In the past three or four centuries most nations in Asia, Latin America and Africa have been the subject of colonial rule. In this colonial rule, the masses of people did not get fundamental education easily. Uncontrolled famines, genocides, the stealing of local resources, mangling of local industries and businesses, all occurred in colonially ruled areas in the World.
As an example, let's take India. Before British rule, the major empire in India was the Mughal empire. The Mughal empire was one of the greatest forces in the World at its peak, the gross domestic product (GDP) of India in 1600 was estimated at about 22% of the world economy, the second largest in the world, behind only Ming China but larger than Europe. By 1700, the GDP had increased to 24% of the world economy, even greater than Qing China and Western Europe. Real wages and living standards in 18th-century Mughal Bengal and South India were higher than in Britain, which in turn had the highest living standards in Europe. According to economic historian Paul Bairoch, India as well as China had a higher GNP per capita than Europe up until the late 18th century.
Up until 1750, India produced about 25% of the world's industrial output
During the Mughal era, there were great advances in observational astronomy, metallurgy, chemistry and other sciences.
After the decline of the Mughal Empire due to the weak rule of the late Mughal emperors as well as British interference in Mughal and municipal court, the British cemented themselves as the sole rulers in India, officially after the 1857 War of Independence.
The literacy rate in 1872 during British rule was only 3.2%
