That's just basic supply and demand and it's not unfair. Jobs where demand exceeds supply are paid more and more until people decide to train/retrain for that job.
You say that's fair, but someone else could say it is unfair. The supply/demand equation you describe suggests how the salaries get decided upon, but that's not the same thing as fair. That's the system we have, but that doesn't make it automatically fair.
