This is a seriously misguided & a gross oversimplification of what happened. You could literally say that about conquest or takeover in the world. The rulers before were shit. We actually helped steal all their money & resources as they didn’t know what to do with them, killed millions of their people just because they opposed us & then now look how badly they govern themselves once we divided them up & placed corrupt leaders at the helm the stupid fucks. Being good at Colonialism doesn’t excuse the incredible vast injustices that this nation inflicted upon others & in return seriously & financially gained from. India was thriving before the British arrived. India was a major player in global trade, particularly in textiles and agriculture, and was one of the wealthiest regions in the world. The British East India Company and later the British government drained India's wealth through taxation, trade policies, and the suppression of local industries. The Indian textile industries were deliberately crushed to promote British goods. India's share of global GDP plummeted under British rule, and famines became more frequent and severe. Yes Railways, roads, and telegraphs were built but mainly just to move troops and extract resources efficiently. By 1700, India accounted for about 24% of global GDP (compared to Britain’s ~3%). By 1947, India’s share of global GDP had shrunk to just 3%. India before the British was doing just fine, they weren’t perfect but they were prosperous, culturally rich & politically autonomous before Britain literally systematically drastically weakened the economy & disrupted & distorted social structures. Don’t you dare change the narrative because you’ve read in an old colonial textbook that the rest of the world savages before the British “saved them”
