What about tax breaks for marriage? As one who favors simplified tax structures, with no favored treatment for any special interest groups, I have a hard time justifying any special deals on inheritance taxes or income taxes for anyone. Current income tax laws don't actually help most married couples much anyway, and sometimes even create a penalty. Inheritance laws are their own mess, and are unfair in many ways. Fix the inheritance laws, but don't use them as a justification for perpetuating the state's meddling in the institution of marriage.
Eliminating all marriage laws sounds incredibly radical. The government's regulation of marriage has come to be accepted as a law of nature - as real as the law of gravity — but why? Why polarize our nation over the government's definition of marriage when the state has no business being concerned about marriage in the first place? Imagine a new unfettered society in which the tradition of marriage is returned to its proper home, in the church, and in the hearts of those choosing to live as one.
