There's plenty of pressure differential in a lifting plate in a positive alpha. There must be in order to impart a net downward acceleration on the flow, thereby turning it. Here, have some CFD: https://www.youtube.com/watch?v=KldLqShzCRM
The problem in these discussion is "Bernoulli" is used to refer to many things, some legitimately physical (mass continuity) and some not (equal time of passage). I like FYFD's point that what we're discussing is how to explain lift to laypeople, not how to calculate and analyze it (which is done every day in order to design aircraft): http://fuckyeahfluiddynamics.tumblr.com/post/121024503205/ev.... We (mechanical/aerospace engineers) know the equations that govern fluid motion and how to solve them, whether you abstract that with Bernoulli/Newton/Kutta-Joukowsky/etc. is up to you and not that significant.
