India is an amalgamation of different states with distinct cultures, languages, and ethnicities. Due to its federalized political system, it is impossible for the disparate states to reach a consensus on economic policies that would be beneficial for the whole country, as each state only prioritizes the interests of its own elites and would rather drag all the other state down if it is unable to secure direct benefits for itself. Historically, multiethnic federations/empires have struggled with modernization and economic development, ie Austria-Hungary and the Ottoman empire. India as a unified nation-state is a myth, Indians would be much better if they were to give up on the idea of India and instead separate out into 3-4 independent nations tied together by a loose confederation.
