You can design the crew around the airplane and you can design the airplane around the crew, preferably both for best results.
Difficult aircraft with undesirable characteristics require highly trained crews. The military know this and have stringent selection criteria, only the best are going onto single pilot fast jets and a fortune is spent training them.
Airbus recognised years ago that experience levels and training standards were dropping and designed airliners to cater for this. Protections to prevent stalling, over speeding and excessive control force being applied were built in. Something goes wrong and a checklist pops on a screen.
These two methods worked well, Boeing put a poor aircraft in the hands of inadequately trained crew and we've seen the results. I'm not blaming the crews concerned, if Boeing had designed a better system and the crew were fully informed and trained in its operation the accidents wouldn't have happened.
