You’re assuming these ‘stay at home mom’s’ are married. And that uncle sugar isn’t the working dad.
I think the article makes it clear that it is an intact family.
Now, I suppose the WSJ author will be chastised for using the term mom when referring to 1/2 of the family unit (excluding the children).
Or recently arrived moms who are unemployable because they speak no english.
OMG, I see what you are saying. They have a sugar daddy, and his name is Uncle Sam. Uncle Sam is paying all her bills. She has no actual real man in her life.
Bingo!
also, assuming that the moms staying home are actually “being” a mom rather than just being a lump on the couch.
