If the Bernoulli effect really was that strong, you could tilt a flat plate downward into airflow, and it would generate lift at any angle up to the point that flow turning balances it out.

What about those Bonneville Salt Flats spoilers? Fast airflow on top, virtually no airflow below. So do they create lift?

They create negative lift.They 'spoil' the lift.
