But if corporations are amoral, why shouldn't they pretend otherwise? It is to their benefit, and they are obliged to make decisions to their benefit regardless of moral considerations.
If a company's job postings said "We are an amoral corporation and we don't pretend otherwise", would that help their hiring?
I agree that we should take a skeptical view to corporations virtue signalling. But I also think even democratic governments have at best a marginally stronger claim to moral virtue. That combined with the challenges of crafting regulations that achieve the desired results (desired by who though?), with acceptable levels of negative expected and unexpected consequences (acceptable by who?). Good regulation is important, but it is fiendishly difficult to do well.
Corps are amoral and we should stop pretending otherwise and if the US wants corps to behave different, then we need to regulate them.
