If you were living in Cuba, would you pay 40.00 or 50.00 (CUP), Cuban pesos, for a 14 watts or 18 watts light bulb?
The situation in the Convertible Unit of Currency is even worse. 3.00 CUC for one light bulb. That is equivalent to 75 Cuban Pesos.
All I can say is that the Cuban leadership were very good revolutionaries, but in today's world they are very poor economic administrators. More common sense and less ideology is needed in the island.
The prices that I am quoting above were taken from today's Granma, Oct 1, 2013.
I recently bought at a retail store 4 sixty watts light bulbs for US $1.50, or 38 cents per light bulb.
