I see your point, but I think there's a danger in trying to prescribe too specifically. The risk is that you end up saying "hey, this field was in great demand and had great pay when I was your age, go do that!". Things change, by the time your daughter is of work age there will likely be new field opened up that don't exist today at all and perhaps some that exist now will have disappeared, shrunk or become much less lucrative. I think there's wisdom to encouraging kids to really think about their choices though in more detail than "this sounds cool!". A good rule of thumb is to ask "what job would you want to get from studying this, and if that doesn't pan out what is the backup plan?" If the backup plan is "I will teach" then proceed with caution.
