Here's where I am with regards to the financial implications of legalizing same-gender marriage... Every equal rights movement has come with financial difficulties. There were costs with racial integration and affirmative action. There have been increased costs associated with providing accommodations for the handicapped.<quoted text>
I think I've already made it clear that I understand, and agree, with your premise regarding govt involvement in ALL marriage. I am not inclined to think it will get out of the business of marriage any time too soon. I also would like to point out that the poster appeared to be arguing that allowing same sex marriage would generate a significant financial burden due to the tax breaks a few on here keep referencing. I asked someone, Brian_G IIRC, to come up with a figure showing the significance of the allegation. Nothing yet AFAIK has been mentioned. These tax breaks are typically found when a pair gets together that have incomes of a significant difference. Most of the gay couples I know have comparable incomes. The tax benefits seem miniscule to me. That said, I'm not the one bellowing about the finacialn damage. Those who claim it will be a burden ought to be able to show their maths.
The way I see it, private and public institutions got away without providing these services for decades--even centuries. It was a social expense that should have been incurred all along.
And until the equality is realized, there will be costs associated with these changes.
The system will balance itself one way or another. As you have suggested, maybe governments will decide that it's too expensive to provide benefits and protections to all married couples, so they will slash current benefits that are only available to heterosexual couples.
But until that happens, same-gender couples SHOULD HAVE access to the same benefits AND protections as opposite-gender couples.
Other countries are managing to do this. Why would the U.S. be unable to do this?
