You are right.Just being white and male after WW2 gave you the golden ticket and now many white people don’t like the change.
Society reinforces the idea that lack of formal education means inferiority in an overall sense , is worth less, and should be paid less. That is the mistake.
When people are denigrated they can either feel shame, or become hostile and vindictive. And what you have here is vindictiveness and hostility. Just like the African-American experience. First shame then the Black Panthers and Black pride….to cure this, people must feel valued and not judged inferior by any other standard other than their character.
