> If people demand evil, they will make evil, if people demand good, they will make good.
This is so naive.
People do not ask corporations to be evil and they certainly don't demand it. People ask for good value and convenience and corporations respond by doing by amorally pursuing that.
However, when you ask consumers if they want value and convenience at the cost of *evil*, they almost always say no.
Corporations have a demonstrated and well-documented history of actively hiding their evil actions because they know consumers are not aligned with them at all.
If consumers "demand" evil, as you say, then corporations wouldn't try to hide it.
Counterexample.
Even when eggs are clearly labeled "caged" and "free range", many people will buy the "caged" eggs despite the clear implications in terms of animal welfare.
Also, while I consider organic food to be mostly (but not completely) a scam, most people don't buy organic. Which can be interpreted as "if it is cheaper with pesticides than without, I will go for pesticides".
In cars, emission control devices have to me made mandatory and almost no one would pay for them. And even with that, people sometimes break the law to remove them (ex: catalytic converter). It is common for all environmental laws.
Of course, if you talk to people face to face, most will tell you that they don't want value and convenience at the cost of evil, but in private, if can turn a blind eye, they will.
And most of these company evil practices are often not very well hidden. Sometimes, they are genuinely criminal, highly secret operations, but they are often not, as criminal lawsuits are costly, and secrets like that don't last long in big companies. But if it is legal and it brings value convenience to people, people usually don't want to look too much, even when some NGOs try to bring awareness.
