The term 'economic planning' and perhaps still more bluntly 'planned economy' contains a tautology... The word 'economy' by itself implies, of course, a co-ordination of activities, directed towards a purpose. It implies a subject, a will, a plan, and a rational adaptation of means towards an end or or a goal. To add planned in order to indicate that this co<ordination of activities has a purpose, does not make much sense or cannot, anyhow, be good usage. Language, as we know, is full of illogicalities.
