In your example, there is an obvious moral argument for an even split. When you&#x27;re talking about a wider social contract, the morality is less clear. How are people supposed to work out what&#x27;s an intentional tax incentive and what&#x27;s an immoral loophole?<p>Although honestly, what are you doing signing such a dubious contract, even with your friend? If I saw something like that, I&#x27;d at least query it, at which point we&#x27;ve probably established a verbal contract for an even share.
