In Latin American cultures, almost everything baked in a crust is savory. Occasionally you will find a sweet empanada but they are not common. The nicaraguans have something that they are crazy about that is made with a very salty cheese and a lot of sugar.
As for beans, they would never think of putting sugar in them. Most of them think that North American baked beans are totally disgusting.
One has to stop and think that the cooking in the United States has evolved by Leaps and Bounds since the 1950s. Before the Advent of Julia Child, cooking magazines, television cooking shows, and now the internet most Americans had never eaten anything in a pie crust except a desert.
