A fair tax (system) or an ethical taxpayer?

An interpretation of fairness based on the equal sacrifice principle is not clear; three taxation rules can be derived from it. Instead of searching for a fair tax system, ethical behavior of the taxpayer should be expected and set as a target. Ethical taxation can be encouraged and the propensity to pay taxes could be reinforced by abolishing the secrecy of individual and family tax returns, setting restrictions on cash operations which are associated with corruption, and gradually eliminating tax havens and offshore areas.

The moral economic man

Economic behavior is multifaceted and context-dependent. However, the so-called Homo Oeconomicus model states that agents are perfectly rational, self-interest-maximizing beings. This model can be criticized on both empirical and normative grounds. Understanding economic behavior requires a more complex and dynamic framework. In the "I & We" paradigm developed by Amitai Etzioni, economic behavior is co-determined by utility calculations and moral considerations. Two major factors can explain the ethicality of economic behavior; namely, the moral character of the agents and the relative cost of ethical behavior. Economic agents are moral beings, but the ethical fabric of the economy determines which face of the Moral Economic Man predominates.
