Well too bad most don't understand what fairness is. Far too many are quick to discount the work or effort of others because they do not understand the work they do. Its like, I don't know how to do that but it can't be that hard so its obvious they have too much. This is especially true when comparing labor that is more physically involved than that which requires more application of mental ability.
One thing most miss out on is they want fairness but don't want to give up their stuff or such because it is so much tied to who has how much stuff, money, and more. Far too many will state unequivocally that those richer than them don't pay their "fair" share when those same people contribute a higher percentage and far more wealth into the system.
This is primarily driven by politicians who profit by dividing people. That is what most people miss. They hear about all the disagreement in government as if that is a problem. In the US the government wasn't designed to be fully cooperative, it was designed to make governing difficult so as the federal government would not overrun the states. Where events were not to be treated with such division there are statements to that fact.
Yet politicians spend more time pitting people against each other to preserve their own status and this is why people don't understand what fairness let alone equality is.
