Well I certainly know a few Dominicans that fit into your catagory but I also know a lot of responsible Dominican fathers. My wife's cousin has four daughters of his own with three different women. He has paid for them all, now he is with a woman with two kids that aren't his and he has no problem paying for them either. Lots of Dominican guys are with women that have kids from another guy and they don't have huge issues with supporting those children.
Same here...
My wife's sister (both Dominican, same class, 4 years of age difference), have been married for almost 20 years, they have 3 kids who are very much fine people... The oldest likes to go out a bit more, yes, but still... My wife's the same, we've been together 13 years now... Obviously, we raise our kids as do my wife's sister, and they do an awesome job...
But then... My wife has a friend who has a young kid who she is unfortunately raising alone as the father lives in the US and supposedly was organizing the papers to go there, but nothing has come out of that and they have been "doing papers" for the last 4 years... The father though, does support the kid... My wife has another more distant friend who was also left alone with her kid... So yes, we know people from both side....
