I don't know how you came to the conclusion that the quality of CS graduates is poor or how that the cause of this perceived lack of quality is somehow due to courses focusing on theory. In my experience very little in a run of the mill CS undergrad program is dedicated to theory so I might come to the opposite conclusion: too many people are focused on learning how to write code with some javascript framework and not how to do computer science. So people miss important patterns and concepts because no one explained to them why they are important. Patterns you have spent years coming to understand intuitively, perhaps.
