Ethical: Relating to moral principles. Pls note that ethics are subjective and every individual has different moral codes. What is considered ethical to an individual may not be to another.
Yes business should be ethical:
Businesses especially large multi-national corporations (MNCs) today are the bedrock of many capitalistic societies, hence they should be ethical in their practices in order to set the moral tone of how business is done in the corporate world, and to a larger extent, the societal values. Businesses will suffer from a lack of trust and reputation especially if they have flouted some ethical considerations. E.g. H&M have been facing lawsuits in Europe for their sweatshops conditions and exploitation of child labour to manufacture their cheap and affordable clothing. It is highly likely that businesses will suffer from fines and increased regulations if they are seen to be unethical in their business practices. This could affect the company profits drastically and potential sales, which will impact on the eventual staff welfare and salaries that they draw. A case in point would be Volkswagen which was found to have cheated on their diesel emission, and being fined 5/hr here could be seen as a blessing to someone in the developing countries). Resorting to unethical means is only a short term measure for businesses, as once reputation is tarnished, it takes forever to build it back up again.
