Some extremely wealthy people have no class at all, while others who are struggling to make ends meet are loaded with it. Class is real. You can't fake it. Class is comfortable in its own skin. It never puts on airs.
Class never tries to build itself up by tearing others down.
Class is already up and need not attempt to look better by making others look worse. Everyone is comfortable with the person who has class because he is comfortable with himself. If you have class, you've got it made. If you don't have class, no matter what else you have, it won't make up for it.
