Isn't that missing the point?
That's like saying knowing all about medicine is useless because most people don't!!
It (algebra, just like medial knowledge ) is useful, both to some individuals that know it and to society as a whole, because some
people DO understand and remember it and then go on from there to USE it!
And the more people learn algebra, the more benefit society will get out of it. At least just for the simplest most basic algebra that you would be most likely to want to use, it is not as if it difficult to learn! I am sure at least 95% of people can learn just the very basic algebra with ease if only they had good tuition. I for one certainly could teach you or almost anyone else it so they understand it (to a basic level -not so sure about the really advanced stuff that involves matrices combined with imaginary numbers etc )
Something doesn't have to be understood and used by the majority
of people to be useful!
