I agree completely. On top of that, it feels like classic "magical" thinking by a manager who doesn't understand technical scope or split responsibilities. Why bother to understand why you've hired so many people before blithely opining that 4/5ths of them are fireable? Who the hell wants to work for someone who says things like that? Certainly not the "high-quality" engineers who are supposedly being separated from the chaff.
