Well, that would depend on what you mean by "the world." Professors have first hand knowledge of a very particular set of social practices and institutions. These tend to be very important practices and institutions, but they are only directly experienced by a small group of people. Someone working at Burger King will typically have participated in a quite different set of practices and institutions. And there are a lot more of these people. Therefore the Burger King employee's experience with these practices and institutions yields first hand experience that is directly applicable to the lives of many more other people than the professor's. I do think it is a mistake to leap from this conclusion to the much broader one that Burger King employees understand "the world" better. Not only does that claim not mean much of anything, it also discounts the fact that the institutions and practices to which a professor is exposed may be more powerful, despite having fewer participants. But I think GP's similar and more specific claim, that "highly educated people are out of touch with the realities of life of average folks," is very plausible.
