I wonder if these same ‘latinas’ would be getting pregnant and having babies if they were back home in Mexico. My guess is no.
Not in an environment where they would have to work to support themselves plus the kid? No way.
The reason traditional village morality was so rigidly enforced is that parents didn't want to support an illegitimate grandchild, plus it lowered the probability that the daughter would find a good husband to support her.
