This is not accurate. The Indian economy was pretty open; the overwhelming bureucratic red-tape started after Indira Gandhi's nationalization program (and other such policies). India under Nehru wasn't laissez faire by any means, but neither was it Communist.
You also have to see the context under which the politicians operated then. Unbridled capitalism had lead to colonialism and the World Wars and led to much oppression for workers worldwide; the Indian leaders were trying to avoid that kind of wealth aggregation and income equality.
