HAVANA - Rubén Valladares just might be one of the most important entrepreneurs in Cuba.
No, he’s not a tourism tycoon. He’s not a tech titan.
Truth is, he makes…paper bags.
“But we are the biggest provider of bags in Cuba,” says Valladares, a slender, middle-aged man who finishes his sentences with the sort of raspy chuckle that helps people get through each trying day on this island.
