There is a lot of Carribbean around to compare the place to, and frankly, it doesn't compare well to present day Cuba as far as quality of life for the average citizen.
As to your personal attack, I don't know... I don't really see anything wrong with enjoying visiting a place. Or with being nostalgic for what a place used to be. I also, for example, think it's a shame that Belltown in Seattle replaced its cool dive bars with trendy restaurants and condos. But it would be a bit silly to blame me for those dive bars having been there in the first place.
