Maybe If I actually met them that would be different, somehow I just dont think a woman who grows up in a crowded home until 19, never gets to live on her own, and gets married to a man her dad picked out and then 2 months later gets pregnant can really truly be happy or free to know her identity... in God or in herself. They just don't know any different because that's all they know.
If something deviates from your own experience and the experience you know, that doesn't mean the people who experience it aren't happy. You could ask the Duggar girls if they are happy. If they are happy, and their lifestyle is all they have known, what's wrong with that? I'd rather see a girl raised in the situation you describe than allowed to date anyone she want to, and fornicate all over the place, go to college and get drunk, and fornicate, and after she was all washed up and used up, with her prime fertility years behind her, decide to convince her live-in boyfriend to 'man up' and marry her and take care of her and the two kids she had with other guys. Then he has to decide how to work the other kid he had with his other baby momma into the equation.
Also, what you describe is probably fairly typical of wives throughout much of history, including Biblical history. Is there anything about that that we should suspect is displeasing to God? Why couldn't she 'know her own identity....in God' if she grew up in a crowded home and get married young? I'm not following your argument.
For a young Christian man looking for a wife, I can't help but think that a woman raised this way, if her faith is sincere and she's got a good, stable personality, could make a good potential wife. If she's very much dedicated to being a wife and having kids, that sure sounds like a better prospect than dating some girl in her mid 20's that hasn't decided she's serious about marriage yet. The stereotype is of men not wanting to commit to marriage, but I've know there are Christian men who've put a lot of time into dating women who weren't all that serious about marriage. That's an engrained cultural thing. People will date, without being serious about marriage--- too busy finding themselves and their own identity.
Btw, I haven't watched the whole series, but I did watch some of the marriage and engagement related episodes because I was curious about how they did courtship. The two girls sure seemed to want to get married to those young men. One of them was the dad's online prayer partner. I wonder if he got to know Jim Bob with the idea in the back of his head that one of his daughters might be a good match. But after the two started online chatting, the girl sure seemed to genuinely grow to like and then love the young man.
The question is, is the father being involved in the choice of spouse displeasing to God? I'd say a definite 'no' to that. In fact, I see more reason to think that God may displeased when fathers are not involved in the selection of the spouses of their children, especially their daughters. Look at the laws the LORD gave about it in the Old Testament. The father gives the daughter away in marriage. He could refuse to allow a marriage with a man who seduces his daughter, for example.
But we aren't seeing JimBob say, "You have to marry this man." He did a little match making. I think the older son met his wife at one of their conferences of people from a family that may also have done the courtship thing. It looks like they picked each other out.
I've got three girls and one of my concerns is whether I should send any of them off to college away from home, or just keep them in the home until they marry. That may involve following them around to college around the world. I wouldn't be totally opposed to a daughter not going to college and getting married young, if the potential match were a very worthy man.
In my wife's culture, consent of parents to marriage is culturally necessary, though not legally required. I'm definitely teaching this to my kids. When they came home singing Rude by Magic!, I sat down with them, watched it, and critiqued the story line. Then for laughs, we watched a spoof of it, "Why you gotta call me rude." They thought that was funny.
