Oh i see the point of confusion. If taken literally yeah that's how it could be read. I read a sarcastic tone in the whole statement. They make an otherwise serious complaint then use a humorous informal slang like "rawdog" which demeans their own authority in the statement.

In this case the sarcasm extends to the word "let" which i think is pointing to how underperforming individuals get diagnosis and medication much more often. That they are given care while well performing individuals are uncared for.

It does fit the definition of the word as well, to allow someone to do something by not doing anything to stop them. In this case the not doing anything to stop them part refers to that lack of provision of care.
