As someone who has grown up in a communist Eastern European country, I would have to disagree. This "experiment" cost many people their lives, simply for ideological purposes. By the same token, you could argue that Nazi Germany was an "absolutely worthwhile" experiment. "Hey, societies with mixed race have all sorts of problems, let's see what happends when we change that variable!" Some ideas are simply WRONG when you try to apply them in practice. (I don't know you, so maybe you've also experienced communism and totalitarianism first-hand; but if not, I would respectfully argue that it's easy to judge something as "worthwhile" if you haven't personally been affected by it.)
