That really, REALLY depends on your parents.
In the individual case. But the article is making the case that in population studies, marital status can be treated as an independent variable and that children from intact parents benefit from that marriage.
So, in that sense, it "really, REALLY depends on your parents" ... It depends on whether or not they're married.
I must agree. But then, I was born so long ago that many social values and practices may have changed. Self-esteem was not a big priority for parents before the 60s. The word "parenting" rarely, if ever, was used. There was widespread use of the terms "mother", "father", "mothering" and "fathering", however.
