Getting down into the weeds like this, no matter what you say, probably isn't convincing anyone of anything.

If you're talking to people who aren't already on board, it's probably best to leave it at "workers deserve far more and CEOs deserve far less." Trying to get any more precise is futile for a dozen reasons, and should be met with something like "you don't need to know exactly how much water a human needs every day to know that someone dying of thirst needs more."
