But some will enjoy that support more than others. Cuban economists say that whites are 2.5 times more likely than blacks to receive remittances, leaving many in crumbling neighborhoods like Little Swamp nearly invisible in the rise of commerce, especially the restaurants and bed-and-breakfasts that tourists tend to favor.

“Remittances have produced new forms of inequality, particularly racial inequality,” said Alejandro de la Fuente, director of the Afro-Latin American Research Institute at Harvard University. “Now the remittances are being used to fund or establish private companies, that is, not just to fund consumption, as in the past.”

The Cuban government argues that the shift to more private enterprise, a pillar of its strategy to bolster the flaccid economy, will allow it to focus its social programs on the neediest. As a billboard on a busy road in Havana proclaims, “The changes in Cuba are for more socialism.”

But many poorer Cubans are frustrated by what they see as the deteriorating welfare state and the advantage that Cubans with access to cash from outside the country have in the new economy.

“As Cuba is becoming more capitalist in the last 20 years, it has also become more unequal,” said Ted Henken, a professor at Baruch College who studies the Cuban economy. “These shantytowns are all over Latin America, and Cuba’s attempt with revolution to solve that inequality succeeded to a certain degree for a time. But as capitalism increases, you have some people more well positioned to take advantage and others who are not.”

At Starbien restaurant, one of the most popular in Havana, the owner, José Raúl Colomé, said it was not unusual for a majority of the clientele to be Cubans who live on the island, rather than tourists or expatriates.
