Cuba's sugar problem = bad government. They were ill-prepared and are facing a crisis. Let's not waste time blaming everyone else. One cannot demand to operate in a static market environment just because their sluggish, archaic government is unable to adapt and overcome. Stop playing the victim card for an ineffective (and tyranical) government. Time came for change and they failed; those commies are lucky we don't allow failing to evolve politically and economically to cause their extinction.
They will get bailed out for this lack of adaptability, but they will continue to live decades behind their neighbors as long as tyranny reigns.
