No matter what someone is paid (or whether they are paid at all), they are a person, with hopes, dreams, feelings, and dignity.
I know you probably already believe that, but it's worth stating anyway.
Our society does tend to treat people like cogs, but that is a problem with our society.
Words influence how we feel about others. We should use words that affirm the dignity of others, then work to make that a reality. Just because most people treat other people like cogs doesn't mean that we should throw in the towel and accept it; much less start doing it ourselves.
I agree that putting a bow on nastiness is messed up, but the root problem is the jerks. If we stop even thinking in terms of people having dignity, the jerks have won one more step. We should spread kindness and dignity wherever we can, and try to get people to name things that imply dignity.
I agree there is a major problem of people with less pay being treated poorly. It seems respect is only given to the high paid, but that is messed up when you stop to think about it. Our real worth isn't determined by our financial status. What if we lose the financial status? Would our friends desert us, our rights be removed, and we end up forgotten?
I for one want to work against the world becoming more like that.
