The tail is not lift, it is a downward force to give the aircraft stability.
The wing is the only surface that counteracts gravity which is lift. The tail down force must be supported by the wing lift force and why some aircraft save fuel by keeping the CG back in cruise. Airbus is one and we figured that ourselves in the Lear Jet by transfering fuel back and being able to reduce cruise power.
