Sure, we could do that, but unless any of those things affect profit, the business won't change. Morality doesn't motivate business, profit/money does.

> Businesses are just groups of people. A business behaves ethically only if the people who make it up behave ethically. We don't lose the ability to criticize them just because they're acting as a group.

Sure, and if people feel morally conflicted an leave the business, they are replaced. If there comes a time where so many people are morally conflicted that there are not enough people to run effectively run the business, then the business will change or cease to exist. Even in that situation, you have a moral issue for the workers that became a financial issue for the business.

Businesses have no morals. The people who run it do.
