Don't underestimate the 320 pilot corps
Ironbutt, you underestimate the 320 pilot corps.
If you insist that previous experience is indeed relevant, let me provide you some data that you might not be aware of.
Previous types flown by the 320 guys:
707, 727, 737, CRJ, ERJ, RJ100, Md-80, Dornier, ATRs, and 320s as well. Glass cockpits and if not, medium, heavy jets among your beloved turboprops.
Half a dozen with CMD experience.
The 320 fleet holds enough credentials, guys coming from different environments, different operations, from light-twins to reputable airlines.
Having said all that, I still think that previous experience is NOT relevant. You pass the selection, you get screened then drilled by the Training Department and you become a GF Pilot.
You put everybody on the same standard.
What you call "euro-brat" and "spoiled child mentality", some others see as an increase in flight safety, having people coming from cockpits where the power gradient is not as steep as elsewhere. They will challenge poor decisions made by commanders that treat their co-pilots in an adult to child relationship.
