The only problem is that this is blatantly false as amply demonstrated
by all the papers that have been quoted in this thread. In particular
you can see images clearly showing that particles don't meet at the trailing
edge by far. Moreover this is necessary so that circulation is created and
there is a theorem in fluid mechanics relating lift and circulation.
Other figures show that the distribution of speed around the wing may be as
unintuitive as possible. So that, even if Bernouilli theorem is perfectly
true, you can get zilch intuition using it to understand lift.
