Superman, when written well, is an aspiration hero, an ideal for us to try and live up to. He has the power of a god but thinks of himself as an ordinary person trying to help out. He's also not the least bit insecure about being made fun of for wearing his underwear on the outside of his outfit.
Superman is extremely emotionally open and basically free of the posturing and fronting that defines much of toxic, insecure masculinity. And there's a reason for that.
Toxic masculinity is all about being afraid. Every behavior is a defense mechanism, a bit of armor against the threat of violence that men deal with every moment of every day of their lives. In the absolute knowledge that no one is coming to save them, men mutilate their entire personalities in order to lessen the chance that they'll be the victim today.
The reason that the wealthy and powerful are less bound by the strictures of masculinity is the same reason that Superman is. They've got less reason to be afraid. The less the world is willing and able to hurt you, the less you need to pretend to be the most dangerous person in the room so it'll think twice and move on to an easier victim.
We all want to be like Superman deep down, to live our lives reaching out to one another instead of lashing out at one another. It absolutely isn't a lack of desire that's holding us back from being like him. It's lack of ability.
Because the thing is, Superman gets shot all the time. People are always trying to outright murder him for being who he is and doing what he does. It's exactly that reaction men very reasonably expect if they tried to emulate him, and the rest of us aren't bulletproof.
