Evangelicals: Why is nobody ever called to be a pastors' husband?

I've been puzzled about this since my college days, when I met several women who said they felt "called" to be a pastor's wife. The obvious answer is culturally-ingrained sexism, but most evangelical denominations ordain women pastors, so it's not overtly about keeping women out of power.

Naively, I'd assumed that such "calls" were dying out. But some recent questions here challenge that assumption.

So I'm curious:

Is it still common among evangelicals for young women to feel "called to be a pastor's wife"?

And: If God calls men and women to the ministry; and if He calls some women to be pastors' wives; why does He never call any man to be a pastor's husband?
