My knowledge here is purely academic, so forgive me if this is inaccurate. Anyways, we were taught that the majority of jets have the wings angle of incidence purposely set at absolute AOA (zero lift line). Granted the addition of flaps would add some lift and any back pressure, trim or pilot input, would increase AOA and thus increase lift.

We were told the purpose is to minimize drag during the takeoff roll to maximize takeoff performance. Is this inaccurate? Do we have any designers on these boards that can speak to the wing mounting of some of the jumbo jets or other jet aircraft? Thank you in advance.
