^ that last statement was mainly in response to the " 'evil-because-evil-rich-guy' is thematically appropriate for Spider-Man." comment. But I can understand your argument even though I don't necessarily fully agree.
I know that your comments are more generally directed, but to clarify my views:
Tbh I've been incredibly disengaged from the MCU stuff apart from my piqued interest after NWH. They have been, in general, so far removed from the source material that I really didn't have all that much interest to even comment on issues of class much less analyze them. I was more invested in the Marc Webb films even though I disagreed with their interpretation of the stories they were adapting. But at least they were trying to adapt something from the source material.
I also don't necessarily fully agree with the everyman/relatability ideology even though I understand it. Mainly because I think it has been flanderized to hell and back to the detriment of the character in the wake of OMD. I didn't like the CEO plot but mainly because it read like another shallow high concept plot to showcase the character's ineptitude as opposed to a more meaningful character-driven story to highlight the character's strengths. Peter as an educator felt more character-driven. And not necessarily because of issues of class but because he began his journey as a student learning, growing, etc. So it felt as though the character had come full circle and had evolved from his experiences.
