> Less freedom for those who happen to like traditional gender roles, now they are forced to work more and adapt to more "modern" gender roles. Otherwise they will lose out massively because the single earner has so much lower salary now

That's an equivocation. There is the freedom that comes from choice (what is not disallowed) and there is the freedom that comes from available choices. For example, homosexuals being able to marry is not the same kind of freedom as if I had a million dollars I'd be able to do what I want.

Those who prefer traditional gender roles can still have them, they just need to compete to afford it, as they did before, or to cut their cloth.
