JQ is right.
I am from Europe and recently visited Nicaragua (GRingo trail but its a start)to discover a beatifull country. Tourism can be good to the industry (Costa Rica)generating jobs. Exchanging my dollars for cordobas and eating, drinking etc... being a consumer (with a very tight budget) I was part of the locals daily business (More of me will have a more significant influence).
Anyhow the whole investing of property, commerce or any other activety will bring benefit to the country as a whole. Living in a world of free market and capitalism some will take advantage but with time, patience , hard work and thinking, Nicaragua has got a good future.
