As usual, W got this story wrong.  The quote was taken from a paper by a Dartmouth College student and was used by W completely out of context with the point the paper was making.  

"Trumbull says the president's speech misconstrued the meaning, which he says should have been clear from his paper.  "It shows that they didn't read much of the article," Trumbull said in a telephone interview.
According to Trumbull, who conducted field research in Cuba, prostitution boomed in the Caribbean nation after the collapse of the Soviet Union in 1991, providing an important source of currency for the Cuban economy. Castro, who outlawed prostitution when he took power in 1959, initially had few resources to combat it. But beginning around 1996, Cuban authorities began to crack down on the practice.
Although prostitution still exists, Trumbull said, it is far less visible, and it would be inaccurate to say the government promotes it.
Even when Castro made the remarks, Trumbull said, he was not boasting about Cuba's prostitutes as sex workers.
"Castro was merely trying to emphasize some of the successes of the revolution by saying 'even our prostitutes our educated,' " Trumbull said. "Castro was trying to defend his revolution against negative publicity. He was in no way bragging about the opportunities for sex tourism on the island."

SOP for Bush. When you're wrong on the facts, just lie.
