Dantes, what ultimately determines what we have to pay a player is what they can get elsewhere. So the key thing to look at for determining a 'reasonable' level of wage inflation is overall income rises of our rivals, so things like TV money, matchday revenue, commercial deals etc. That's why, contrary to your theory, Man Utd have been able to not only avoid a rising wages/turnover ratio, but actually keep lowering it, because they've been able to increase their revenues at a faster pace than their rivals.
