in America to be in a major you need 500 hrs Jet but no turboprop (so where do you get those 500???)...
Through the regionals... most are recruited onto B1900s...Saabs etc and upgrade to small jets ultimately moving on to the big boys seats in the majors.. unfortunately, because of the seriously crap salaries offered by the regionals anyone with a few hours under their belts avoids them and they're operating with some hopelessly inexperienced people even in the left hand seats... hence some of the incidents of the recent past.. You don't think a 10k hr capt can screw up ?
If he can make a bad decision about trying an approach better avoided, what chance is there that he'll debate it with a newbee on the right who barely knows which way up he's flying ?
As far as I know Boeing are still producing a/c requiring 2 crew... not one and a bag-carrier. A chimp can be taught to push a few buttons.. decision making skills come with experience and if CRM is to be anything other than lip-service there has to be real interaction between two pilots of reasonable experience.
