I'm guessing kiddnappers outside the USA fall into two types - those who take high value executives for ransom and those who take lone travelers for ransom (very few I'm guessing).
In the USA I've seen stories about a lonely guy gets picked up by a woman/young woman and thinks he is love. She gets to know him and finds out how much he is worth. Then the woman's boyfriend kidnaps the lonely guy and demands ransom from the family. I'm always skeptical when someone starts to ask me about my money.
