I don't have the answer but here is a report of how not to get the answer because the question is wrong ! (BTW, I am very big on the concept of asking the correct/relevant question, a legacy of my reading of Martin Heidegger - I will blog on this in a future blogpost).
Which of the following question is wrong?
“In your opinion, what is the ideal situation for young CHILDREN: mothers working full-time, mothers working part-time, or mothers not working at all outside the home?”
“In your opinion, what is the ideal situation for young CHILDREN in two-parent homes: both parents working full-time, one parent working part-time, or one parent not working at all outside the home?”
