If I read the survey correctly, 66% of the dads are OK with the wife as homemaker. Thats 2 out of 3 which probably covers those with more traditional values.
I think it often depends more on what their own mothers did or what their sisters do than actual traditional values. My dad was as conservative as one could get but since his own mother worked and some of his aunts, his sisters also worked, I think he saw that as better even though my mother would only work if it was a job she could do from home.
It just depends on the couple but it's something they should decide on carefully before marriage and be sure they agree on.
