about jet engine

Hi all, i am new to this forum, i just want to ask a question, may be it is quite silly, but still hope someone can answer.

As we know that the lifting force is provided by pressure difference, and by bernoulli equation, the faster the air will decrease the pressure. AND the jet engine is used to accelerate the ambient air to provide thrust. So, will it deteriorate the lifting ability and why not building it above the wing? thank you
