"What is justice/fairness?" is one of those philosophical questions that will never be closed. Claiming that there exists some ground truth definition of fair is, frankly, naive. Terms like "just" and "fair" are over-loaded and refer to an ephemeral concept for which there are multiple, competing explanations and theories. No consensus or ground truth exists, so it's always fair game to introduce new explanations and theories. This has been the case for at least thousands of years. Progressive politics didn't "redefine" fairness in any meaningful sense. Whose definition of "fair" isn't a "redefinition"? Rawls? Plato?
