Madam, – John Moran's piece regarding Cuba's creeping socio- economic changes (Opinion, December 13th) made for interesting reading. Especially telling was the ethos espoused in the recently published document entitled Draft Guidelines for Economic and Social Policywhich states "as we update our economic model, planning will be paramount, not the market." Something, perhaps, to be gleaned from this nearer to home? – Yours, etc,
