Lee-Lee,
The guy I dated all ready had his green card when I met him. A dominican can only get a green card (if he's using a woman to do it) only by marrying her - this guy was never married prior to us dating.
There are other ways for someone to get a green card, but marriage is probably the quickest way these days (It was a bit easier say 30 years ago).
I definately agree with you when you say that people can be driven to do certain things out of desperation or when they are faced with a certain situation (I think that was the jist of what you wrote).
Yes, I also believe that there can be DDD (I can't think of one off the top of my head but, I'm sure there are many). I don't believe that everyone is the same and yes, the reputation of this culture (dominicans) has ruined it for many. SOOOOOO, with all of that said, I guess you just need to use common sense and be on the look out.
Sorry about the scumbag you met. Just be thankful! Next time, if you come to the DR looking for marriage material (or a serious relationship - not just a "goodtime", chances are you won't find it in a resort.
You'er probably better off finding a dominican that already lives in the States that frequents his homeland and is here on vacation. You might find one at nice local bars in Sto. Dgo. (I'm out of the dating scene so I can't be specific). The point is, men working in resorts meet a lot, a lot, a lot of women. Not that one can't be DDD!!! .... everything's possible.
