Your perspective is completely wrong. Cuba isn't Disneyland, it's a country with a population of over 11 million people. Tourism is currently a significant source of income for many on the island, and even professionals with university educations are drawn to the resorts out of necessity - I know an air traffic controller who works full-time in Varadero and conducts private tours on the side to earn much needed money. He's one of the lucky ones.
Cuba needs industry and business. The country introduced reforms a few years ago to encourage small private enterprises, but access to capital and markets has kept people from being able to take advantage of those changes. As it stands, there is foreign oil investment from companies like China's Greatwall and Canada's Sherritt, but the nation's basic infrastructure is in crisis; a lot of the infrastructure was obviously built under the guidance of Soviet engineers -- concrete apartment buildings dot the outskirts of Havana that are familiar to anyone who has visited Vilnius or St Petersburg. The electrical poles are a classic Soviet concrete design, as are the 1970s and 1980s era bus shelters. Even shop doors cause me to do a double take, because they're right out of my 1990 memories from the Baltic states.
But anyway, I digress. What Cubans need is access to capital and encouragement to start small diversified businesses that extend the economy beyond rum, cigars and tacky booze holiday tourism. They also need access to the US market in a manner that isn't exploitative (American companies that see the island as a cheap labour source for large manufacturing facilities would not be beneficial, because the wealth would flow out of the country, as an example).
