Because the Cuban governmental monopoly on the tourism industry, corrupt politicians enriching themselves at the direct expense of the people, vast inequality between the nomenklatura and ordinary peasants, and forced labor in the sugarcane fields for schoolchildren is so much better.
The government may control the tourism industry, but the tourism industry is also very beneficial to anyone even remotely associated with it. It's one of the few ways foreign dollars can get into the country. I do agree that there are probably plenty of corrupt administrators out there, but those occur everywhere.
As for forced labor of schoolchildren... where the heck did you get that? The Cubans have a very extensive education system. They may not have laptops for every child but every single one receives a full education, including college and university fully paid for by the government if they desire. There is mandatory military service, but that's actually pretty common anywhere other than north America. The only thing really holding them back is the US embargo.
Oh, and Cuba drastically cut sugarcane crops with the collapse of the Soviet Union, who used to purchase it from them at an extremely high price. Most crops these days are tropical fruit, potatoes, cassava, tobacco, and some rice.
