Re: Just to play devil's advocate here
You're making an assumption about deviation from a baseline. We would need evidence to support that assumption.
(And then we should also consider valid business goals, such as cost saving, that would militate in the opposite direction. Given a choice between a 25 year old earning $50k and a 50 year old earning $100k with the same transferrable skills, what's wrong with firing the older person? Sure you can say (speculate) that s/he actually has a great many more skills that aren't being properly valued - but on the other hand, they may also have a lot of baggage/bad habits that are actively holding them back. We just don't know.)
