I, for one, am not comfortable when I find out that the two pilots in the front office have a combined total time less than 5000 hours. Sure I can understand it on a Caravan, or a 210, but in a 737? No. Scares the pants off me to think that I'm trusting my life, and the lives of my family to some kids who're younger than my own sons (And I'm only 50).
You are completely wrong my friend. Some "kids" as you said, might be much better than some others older. Of course they need experience, but when we all begin operating a new aircraft, doesn't matter the age. Know the aircraft, what are you doing and safety overall, not the age. Just my opinion.
