You could make the same argument about public schools. Having been run by liberals for the last 40 years, they're pretty much worthless now.
Now, now, now, they're not completely worthless! After all, there are a lotta kids nowadays who know how to put a condom on a cucumber!
Not sure how they use that supreme knowledge though, since I've never seen a cucumber that needed one! But hell, if they teach it in school, it must be needed somewhere!
