I know of a chica (friends info) that bought a house in Miramar, with the money she earned entertaining yumas, so there are some that are doing VERY well. Not the norm but they exist.
Although a long story, which i will not relate, i ran into another that was making up to 2k/week plus expenses.
All of this in the late 90's. I can't imagine what a sophisticated, well dressed, model georgeous, perfectly groomed woman can make these days. I am not talking about a 20 something. More like a young looking 30 something.
Another had some idiot Yuma buy her a very nice house. The moment she moved in, the rest of her family moved in. The next trip, her Yuma shows up at the door, she, basically, told him to shove of. Wouldn't let him in.
