Well, that's an interesting side discussion in itself : what is value. Let's leave the edge cases out of it, and rephrase : if you're pursuing a legal activity using legal means, and you've made a legitimate profit from selling honest products then you should be proud of what you have done. Think Steve Jobs rather than Pablo Escobar. Even then, some would (and do) say that Steve Jobs flogged a lot of overhyped and overpriced products to uncritical acolytes. I would answer that he did so honestly and the people purchased of their own free will, so they did receive value for it. I'd leave morals out of that it because morals change a lot over time and between societies. As a rough meme - legality is kind of codified morals of a particular society. So if you're doing things within the legal framework then you're OK. Of course there are douches making illicit profits doing illegal and immoral things. But these people would be conducting illicit activities no matter what the framework they operated under. At least in a free society you're able to avoid them.
