My daughter is a Peace Corps volunteer in Costa Rica. She's been there about 8 months and from the sounds of it, Colombia may be a better bet. A lot of people are relatively well off especially in San Jose. From land sales to gringos and tourist developments many people in the boonies have made money. However they are mired in a culture of petty thievery, violence, alcohol addiction and general depression. To be sure she's in a remote area up near Nicaragua but it really sounds dismal to me. There is a lot of money floating around and opportunities for improvement but they just seem to be mired in quicksand in terms of their willingness to do anything about it. I plan on spending a few weeks there in February to check it out myself.
