Public Sector: 

"... the actual performance of the public sector has not
conformed to the role envisaged. Far from promoting private sector
development and channeling it in socially desirable directions, there has
been poor performance in supplying key inputs at a reasonable cost, in
appropriate amounts and at the time and place where demands arise. Thus it
has acted as a brake on private sector development. Choice of location,
employment and pricing policies of the public sector have become so
politicized that efficient development is an exception. Far from
generating resources, the public sector has become a monumental waste and
liability for taxpayers." T.N. Srinivasan, in "Planning and Foreign Trade
Reconsidered," in Subroto Roy and William E. James (1992). Foundations of
India's Political Economy: Toward and Agenda for the 1990s. New Delhi: 
Sage Publications.

Import Substitution and the Private Sector:

"As soon as Indian manufacturers are physically capable of producing
substitutes for imports they are given absolute protection - not just high
tariffs that leave buyers the option of paying a premium for preferred
imports; imports are flatly banned. 

"No finer hothouse for a luxuriant growth of industrial inefficiency and
high costs could be contrived. Banned lists come into effect as soon as a
single producer or two or three can meet the current needs of the market -
long before internal competition can provide any effective disciplining of
costs; indeed Indian manufacturers are encouraged from the cradle to learn
the skills of anticompetitive collusion." John P. Lewis (1969), "Wanted in
India:  A Relevant Radicalism." Centre of International Studies, Woodrow
Wilson School of Public and International Affairs, Princeton University.

One socialist vs. another:

"... as a result of faulty planning under the Nehrus, the country has
remained poor and underdeveloped even after thirty years of Swaraj. Nehru
had blundered ... His daughter made matters worse by her wrong economic
policies, and authoritarian methods. The result was more unemployment, more
poverty, more corruption, more inflation and therefore, more discontent
among the people... The radical Gandhian approach alone can solve the
stupendous problems of poverty and unemployment and take the country out of
the morass of stagnation in which it continues to find itself. " Jaiprakash
Narayan in a Foreword to Gujral, M.L. (1979). Economic Failures of Nehru and
Indira Gandhi. New Delhi: Vikas Publishing House.
