Yes, lots of good has come after independence from British. Education levels increased, Industrialization, better food security, stable borders - less wars - overall economic stability and better growth, Infrastructure has improved roads go to remote villages, electrification of remote areas, less corruption etc etc.That was not the question. Did anything good come out of the rulers that preceded the British ?
Democracy and right to vote is the best thing, elections should be held every 3 years instead of 5. And there should be right to recall, so people can call a vote to pull down a elected government, if it goes back on its election promises.
