I know a guy like this. He's 19 or so, his dad recently passed away while surfing. His dad lived the same lifestyle. They come from a wealthy family, they don't work at all, all the money comes from huge banana plantations (relatives take care of the business). I estimate they make anywhere between USD 20,000 and 30,000 a month in a country where the minimun wage is USD 366 a month. Not bad at all for never lifting a finger.
