Proverbs 31 already says that a good woman is hard to find.
That really makes me wonder about the state of Biblical era women, were they that bad? I am sure all of them were virgins when they married and were good with household duties, submissive, etc. What criteria is Solomon using? The Proverbs 31 woman is described as more of a manager, so she would be older. She is also industrious like a workhorse.
Note that looks/external beauty is not mentioned once about the Proverbs 31 woman. Nor is there any mention of sex/marital duties. So, this makes me think she is a bit of an older/mature woman.
But we know Solomon appreciates external beauty; that's why he had a lot of wives and concubines.
In any case, I do think Proverbs 31 describes a role model wife.
