Fair.

Here's how I see it.

I buy a lot of stuff online. I enjoy not having to pay taxes. I do not have children. People with children use more government resources than I ever have or will AND they get tax breaks that I will never get. So I'm already subsidizing them. And they're completely fine with that. Any time I can get something tax free -- even from Amazon -- then more power to me. And them.

When I can stop subsidizing breeders, we can start talking about "fair" and "unfair" when related to taxes.
