I thought UP gave a generally well-reasoned examination of my post, but perhaps inevitably a few oversimplifications crept in . (Not that I'm one who never oversimplifies.) A lack of time compels a short response right now, but I intend to give a more detailed reply later. (I have to do as Prince suggests, forgo the present for the future.) However: I don't think Fidel was suggesting that the future generations be ignored, only that the presesnt generation could NOT be ignored, which was effectively what the Alliance for Progress would have required.
Second, when you are talking about sacrifices, you have to keep in mind the goal for which the sacrifices are being made. I was a little uneasy at the thought of comparison being made between Fidel's sacrifice of the people's freedom of speech for the goal of material progress, class levelling, racial equality and national unity on the one hand and Bush's sacrifice of freedom in the name of "security" - - security from an artificial boogeyman of "terrorism" cynically created from the ashes of the WTC in an eerily similar replay of the Nazis' utilization of the Reichstag Fire to smash German democracy.
Third, I think it's important to realize the distinction in degree between interference with consumer choice, and the broader concept of interference with "freedom," which of course encompasses a much wider range of restrictions. Neither one is ideal, but you do have to keep a "lesser of two evils" in mind, both in comparing the two cases of a lost "freedom" and in comparing the consequences of the freedom or freedoms lost with the alternatives of providing full freedom and facing the consequences, economic or otherwise, that will result.
Fourth - - and without going into detail here - - you need to consider the flexibility that Fidel was able to exercise after taking the first steps into Marxist-Leninist policy. As the situation seemed to dictate, he has shown the ability to advance further or retreat back on the Marxist-Leninist road. For example, the Mercados Libres that he was permitting farmers at the time of our second visit to Cuba. I mention this in terms of the alleged "sacrifice" of future generations - - as the problems of those generations manifested themselves, it was possible to change tack to deal with them at the time. So attending to the present generation is more of a risk to than a sacrifice of the future generations. It is one way of ensuring that at least one generation is not going to get fucked. The others still have a fighting chance, IF you have relatively flexible leadership.
