A well trained MPL with 350 hours and a type rating is a lot more qualified to fly a passenger aircraft than a guy who has 1500 hours towing banners in a Cessna.
That gets back to the training channels themselves. The USA relies on military trained pilots, professionally trained pilots from Purdue, Embry Riddle, etc. and a group of people who climb their way up the treadmill beginning with Private licenses to CFI to building hours any way they can, whereas many non-US recruit non-fliers and put them through an
ab initio intensive training program that ultimately leads to the right seat.
In the end, rigorous standards throughout nations and airlines are important. Unfortunately, it will never be so, though the majors try.
That’s quite a range of training. But more hours of diverse experience will always be better prepared (and in higher demand).
