I can't really add much here that others haven't already said better, and tempted as I am to wade into the philosophical waters here on just deserts, concepts of fairness, and supposedly free markets, I think it would be better for me to refrain. This thread is already teetering close to political territory, and at least one mod has already expressed his being bored of this thread. So, in before the lock, and all that jazz.
I will say one thing, however: the historian in me always wants to look backward for answers when feasible. So, what did great swaths of the medieval world, for instance, think of merchants and so-called "free markets"? I will paint with a very broad brush here, but typically speaking the merchant classes were treated as being loathsome. Why? The reasons are many, including ones that are rooted in anti-Semitism, religious dogmatism, the desire of feudal lords to concentrate power in their own hands, etc. In other words, a greatest hits medley of all of humanity's more odious reasons for moral and civil rigidity.
But one reason, however, isn't just charmingly quaint, but also echoes some of the sentiments here. (If it matters, it echoes, perhaps faintly, my own.) The reason merchants were hated was because it was thought they didn't actually contribute anything vital to the community. They were nomadic by occupation, so they didn't lay roots; they didn't fight, save souls, or grow food or build bridges, but rather sold the results of others' work; oftentimes, what they were selling were baubles or worse; but more than anything, their sole regard was their own wealth and not the betterment of anything other than themselves.
You see, in the medieval world, such greed expressed in this hyper-individualistic manner was not just evil, but an aberration to the natural order. It wasn't the "good economic sense" or an expression of "common nature" that we, raised in a neoliberal world, would necessarily view it as being.
Of course, I am generalizing, and I don't wish to be mistaken and thought to be advocating for a return to a feudal order. Even Marx understood that capitalism was greatly preferable to feudalism. Still, I think what many in that world despised in the merchant classes, feels just as relevant today as it did then. Tobacco is a luxury good, so I'm not very concerned by a handful of people selling overpriced tins on the internet. But I do see this same kind of behavior used in the selling of necessaries, especially in the United States as it regards healthcare. That's evil. Only, we are conditioned to not treat such as evil, but to treat it as an inevitability and expression of some entrepreneur's infinite wisdom and grit. Perhaps we aren't as far removed from medieval serfs in some regards, I suppose.
