istory provides a plausible answer. For nearly a century, India was under comprehensive colonial British rule. As can be rationally expected, the government that the British imposed on India was not primarily directed towards development, but rather towards extraction. That is only reasonable because wealth extraction is the rationale for colonial rule.
The British, therefore, created the institutional structures, which necessarily includes the government that controlled India through comprehensive government control of the economy. This structure administration and control was left intact when the British decided to leave India, and was taken over by the government of Independent India.
Indians did not become free of a controlling—and extractive—government.
