i hate how this article confuses 'wanting a stay at home wife' with gender equality. so according to this article, having this preference must mean they are not in favor of gender equality.
Similarly, it's stated early on that millennials were expected to see greater parity between the sexes in most roles, especially professional ones. If that's not happening, and if people are swinging back towards preferring men in the position of 'earner' (and therefore in a position of power), it's not hard to make that connection.
It's definitely true that they should have been more explicit about it, rather than seeming to conflate the two without identifying one as a proxy for the other, maybe.
