According to what Scot posted, having gays get married is a money-maker for the government. So where is my tax break I'm supposed to get because I'm married? Also, according to what Scot posted, government spending will go down as a result of allowing gay marriage. So, where are all the goodies I'm supposed to get as a result of being married? The point is that the economic "benefits" of marriage are illusory. If you single people expect tax breaks and government goodies as a result of getting married, don't bother. I'm still waiting.
Imaginaldisc is right here Meadmaker. Not zero-sum... Besides the box of the more intangible “goodies” we already typed about, my material loss is not always your gain; sometimes we both win.
As I pointed out a number of times, I’m in the odd situation where I could break about even. We could get about $5K/year in welfare, or, if we had legal marriage, we could just keep $5K/year of our income. For personal morals I can’t take the welfare we could due to our legal classification as “single” (not to say these threads don’t make it all the more tempting

). But many gays do take what they legally can, and some get more and some get less (some legitimately, some not, imho), but those studies show the results. The results seem to be that we all pay more to keep gays from these legal rights and responsibilities.
You could either take 5K of our $, then add on the costs of pushing it around the government, and then give 5K back as a benevolent big government “donation to the poor”, or you could just let us keep what we make. Surely you can see one is more efficient than the other.
If you’re worried about the loss of a job for a government pencil pusher, we could pay them to do something more productive than juggle money; like cancer research (What I'm currently doing

).
Furthermore, I don’t think these figures get near the actual cost in productivity. If something happens to my homemaker, my productivity goes out the window. It’s in society's best interest for homemakers to have health insurance (and unfettered access to the household income if, alternatively, something happens to the person making the money).
