Here's an article regarding the subject matter at hand first of all:

I believe the price is 39.95 (Not that bad to be fair, but again, weddings cost a ton, you'd look to save anywhere you could, plus it goes with the cultural norm). This price is waived for WOMEN when marrying, but not for MEN.
What would they gain? By my standards, nothing. But by their standards, they would gain a more patriarchal society. When laws are passed, a lot of time and energy does in fact go in to what is said in them. It is by no mere accident that this law exists. True, in a truly capitalist society it would be best if both men and women (and children too, in a truly capitalist society) would all work. We do not live in a truly capitalist society though here in the states; although we worship it enough you would think we did. We have child labor laws, welfare, unemployment, worker's comp., destruction of slavery, civil rights, vacation days, sick days, break rooms, UNIONS... none of these help a capitalist society (at least by the book anyway) they get in the way of profit. I could tell you how each of them does so, but I'm progressively getting more and more off the subject at hand.
