When I was hired in the regional industry they wouldn't even consider you unless you had 3500 hours.

It took 8 years to upgrade with several years of reserve.

I think 4,000 hours to take command of a 110 million aircraft, is more than appropriate not only for demonstrating patience and commitment, but building critical experience.

A fancy type rating is useless if you don't have the indoctrination to flight crew management and developing your own hybrid of leadership by observing and being mentored by those before you.
