For a variety of reasons. First, it's quite possible there is no "cure." The world could wake up tomorrow, collectively think "we should cure stuttering" and throw billions of dollars at it, and still come up with nothing. We're at the point we're still trying to figure out what causes it. There *is* ongoing research into this, but until we come up with that cause, the chances of curing it is almost nil. Second, it's something that affects about 1% of the population in a completely non-fatal way. And while stuttering is a big deal to *us* who have to live with it, to the normal person there are causes out there that need the resources much more than we do. Third, and while this may be hard to accept, we're just more able to live with it more easily than people with other, more serious, conditions. Most of our problems with stuttering is the emotions that come with it. Speech therapy, while certainly continuing to still try to improve fluency, is moving more towards trying to get us to accept it. When we are able to do that, stuttering becomes not such a big deal. It's still something that we have to deal with, and we have to accept there's certain things we *can't* do, but if you're able to get rid of at least some of the emotional baggage that comes with stuttering, it becomes much easier to live with. Fourth, a lot of people just don't know we even exist. I've encountered people who didn't even know what stuttering was until I met them. With only 1% of the population stuttering and a lack of representation in pop-culture, a person can quite easily just never hear of the concept.
