As others have pointed out, speech therapists ("speech language pathologists", in the US) cover a broad area, most of which has nothing to do with tasks like correcting speed impediments. Many SLPs work in medical and rehabilitation settings, often with older patients. (And indeed, this work generally pays better than school settings.) Swallowing is a major topic, since not being able to do this competently can have fatal consequences. Beyond that, SLPs deal with a number of practical cognitive issues. Some of these are related to language specifically, others with related processes. If you've had a stroke, you might have severe problems generating spoken language, even though you can still generate written language without trouble. Or, you might have difficulty with basic planning tasks that we usually take for granted (e.g., what exactly do you need to do to mail a letter?).
