Apparently there is some division in the commentariat as to whether or not this shouldn't be an acceptable form of marriage.
I believe everyone has the right to marry, regardless of sexual preference. For some people being alone is what feels most natural. Shouldn't they too be entitled to tax breaks?Sure, why not? And this way no one will ever interfere with their right to visit their spouse in the hospital.
(I also like the suggestion that this approach to marriage really streamlines the adultery process.)
I guess we've reached the point that the two-parent family has been so completely undercut that no one remembers why married couples were given tax breaks at all. If mostly we're raising kids with single or divorced parents, what's the point? In fact, it's downright unfair: the married couple already has natural advantages. They shouldn't get a tax break, too: the tax breaks should go to the ones who are doing it the hard way. (As, indeed, they already mostly do, since EITC is tied to relative poverty, and poverty correlates strongly with these "hard way" types of families.)
