Transparency and accountability are of the upmost importance. I want to be sure the Commander in Chief is making decisions based on what's best for the American people and not based on what is best for his or her business/business partners. Without making tax returns public, there is no way we can be sure that our interests as citizens are actually the interests being represented. Additionally, all public officials should need to prove that they in fact pay taxes. If you are not willing to contribute to the system, you should not be allowed to participate in it politically.
