&quot;that the law states should be taxed&quot;<p>&quot;though legal, is immoral&quot;<p>There is the problem... the law is an expression of what is acceptable. If we start saying &quot;though legal, immoral&quot;, then things become far too discretionary.<p>Instead of something obvious, like tuition, let&#x27;s say I deduct donations to a registered charity that gets accused of financing terrorism. Should I be prosecuted for avoiding tax in a legal though immoral way? Some people would say giving all one&#x27;s money to a church, and deducting those donations, is an immoral avoidance of tax.<p>All we have to go on is the expression of the community&#x27;s moral taste through the law.
