I'm grateful I don't think I have to worry about this either, but I'm always on alert. You never know even with the best of people how a trauma or health problem might change something and change a relationship. I don't want to get complacent.
But, I definitely see this risk from a prior relationship of my own. It was just a risk, but there were definitely some red flags around things that would make him feel emasculated. Our society is just so fucked up to raise boys to be so fragile and precarious in their self-worth. I feel pretty bad for them except for the fact that the people they take it out on suffer even more than they do.
And I absolutely agree that this is a problem that crosses economic class. Even though society has gotten better about encouraging and opening spaces to female achievement, it has not gotten much better (IMO) about the implicit ways girls are taught to defer to males, to please males, and to placate males. Therefore, even if you are doing something that is celebrated, a male in your life expressing displeasure means something is wrong with what you're doing and it's a priority to resolve that conflict. But this is the best time to prevent controlling and abusive behaviors before they get started.
Until all women, of all classes, aren't intimidated by male anger, this is a risk people need to be aware of.
