"When you empower dummies, you get bad decisions faster." -Rich Teerlink, Harley-Davidson

There are alot of generalizations supported by studies, and almost all of them are wrong. The closest they come is "surgical precision"(and that's a poor example in my experience, as attested by a crooked leg).

The key is the embedded intelligence and purpose of any employment situation. "Motivation" is a throwback to exploitation, not contributory usefulness. The worst types of "efficiency experts" are those who only count beans and are not concerned with any sense of why a job even exists. The 4 types of motivation listed are not types of people so much as choices their environment allows. The USA is a monetized environment, and the culture is habitually dollarized. Most people actually hate it, but take advantage of its conveniences. Those use cases lead to a belief that money is all that matters to a majority, but a privileged few feed and groom that belief. Government service (like the military) provides a working environment outside the tooth and claw 'efficiency' of commercial enterprise.

Aggressive psychopathic capitalists are lions that would eliminate all of the herd except the few they need to eat. (or anything their servants don't serve them).

Managing which employees are necessary starts with asking what they are supposed to be doing, not with how much someone else didn't (comparing gov't to private).

The best military is one that's trained and waiting, not a few heroes always desperately fighting against poor odds.

The best government is supposed to govern least, but that depends on a population that needs least governing. Does the latter sound like the people taking over these days?
