His family had money issue when his dad left at 15 when he was gifted with cosmic powers. A quick 3 years left before he becomes a legal adult. A large chunk hispanic/Latino and Black families have money issues from birth and we don’t get super powers to make up the difference.
His father was a drunk who took a crap job to help provided for his family. Which he did. He was a drunk ,who as of yet to be revealed, never laid a hand on anyone in his family or from what I can tell never verbally abuse them in anyway. He was a drunk who took care of his family. So Sam’s a little embarrassed that his father’s in constant state of morning of his crap life, big deal. There are kids who have a hell of alot worse and we don’t get to rube elbows with Tony Stark whenever we feel like it.
Now the stuff with his cloned father, you got a case there. But were talking about Sam’s weak ground for being a minority as to why he should get a push for a movie over a character with established history of well recieved stories and more of a fanbase. Just to add further that part of his history came after the guy was given the ability to fly through space and blow up planets with a wave of his hand.
