I think a culture has developed -- in the United States specifically -- where we expect companies to act according to some undefined ethical principle. We're upset when they don't pay taxes, close factories, pollute the environment or whatever. The problem is these principles are always moving goalposts and more often than not, immeasurable. A business exists to make money. That is a concrete and measurable goal and thus one that the organization is made to pursue. If a business it not in it to make money, it's something else: perhaps a non-profit, an NGO, a union, a cooperative, etc. There are places for organizations that don't exist to make money, but publicly traded exchanges are not it. It's really the responsibility of communities to plan, governments to regulate and enforce and people to rationally choose the best for themselves and their community. As pointed out above, there are a variety of ways to do this, it's a matter of choosing the right ones.
