Perhaps you're looking at this from the wrong angle and timeline.
Any perceived antipathy can have developed in the past when 'one man bands' were in a system that often allowed them to remain that way. That attitude can be prevalent in two crew outfits due to history and culture. The are still parts of the world where airline right seaters are there to yank gear and flaps.
As to today, it's a fact that many fleets in the airline world have their 'problem child.' Often just left to serve time until retirement as dealing with it comes under the heading of 'far too difficult.' That probably explains much of the problem in perception of single crew types in the modern world. Not fair but that's how it can be. It can be an uterly alien culture for you to have to consider.
It is entirely possibly that the entire pilot hierarchy of a significant airline came through an ab initio cadet system and have only done 10 or so solo hours in their careers - different mindset n'est ce pas???? Think about it.
