While I too disagree with some of the tax benefits afforded to homeowners, particularly with regard to long time homeowners here in CA, no, I would not consider that unethical. For one, there are probably more homeowners and parents than billionaires, so if they vote to give themselves certain tax breaks, even if I happen to disagree with them, I don't view it as a "corruption" of democracy. I'm sorry for using the word "corruption", it might not really be appropriate but I'm tired and couldn't think of a better term. At the very least, politicians seem to be pretty straightforward regarding tax breaks for homeowners, the process of taxation and financial lawmaking seems significantly more opaque to me. I view tax avoidance on the scale of hundreds of millions, or billions of dollars, differently than tax avoidance on a much smaller scale, even if both are perfectly legal. I admit this may not be a very good way of looking at things but I can't help but feel that scale is important here.
I hope my posts didn't come off as a "rant", that was not my intention and I deliberately tried to make sure to point out that I'm not concrete in some of these views. I like coming to HN largely because ideas can be challenged in a respectful manner, I apologize if my posts came off as rants.
