I feel like Luthor was a better counterexample for this before the model for his billionaire redesign was elected President of the USA.
Even so, Luthor hasn't had quite the same volume of appearances as Iron Man, Batman, Captain America and the other rich superhero tropes.
People have grown up reading comic books and watching movies about generous billionaire superhero saviors. They want to believe that exists because it's what they've been taught justice looks like.
Some provide screen-reader instructions, but most places barely remember blind people exist. It's another example of people with disabilities being ignored and marginalised.
And then even if they do remember blind people exist, they probably forget there are people who aren't blind who can't do their tests for other reasons, like dyslexia or dexterity impairments.
And then you have hCaptcha who makes disabled people to sign up to their database to use their cookie.
How convenient that a counterexample can't be named
