Earlier quoted context omitted.
You don't have to make things worse, adding insult to injury. A 'hi' and smile costs nothing. Please at least give that. We're not asking that you give them part of your salary.
I'm not insulting the janitor. I'm insulting myself. And you. And everyone else who works at the company who steps on him. I'm saying, that a "hi" and a smile is utter bullshit. We all know we're stepping on him and a "hi" and a "smile" is opium to make us feel better about ourselves. You completely misinterpreted the post.
You're not making it better by ignoring him. You're making it worse.
You can't change capitalism. But you can change the world by adding humanity for the people you pass in your life.
Not doing that adds insult (ignoring) to injury (unfair compensation).
Believe me, I know the feeling of looking at my salary and feeling embarrassed.
