It's a vicious cycle. In CAS, the default is YA, so of course people will play YA more, because creating a different age takes another step. Then EA will see that more people are creating YAs, so more things default to YAs, so people play more YAs...
Sometimes I forget to change the age when I create a character in CAS, so I end up with more YAs without wanting them.
I mean, there are other issues like the shallowness of society, overrepresentation of YAs in media, etc., but the CAS default really isn't helping.
