How is it fair for a big fat dude to walk past a bunch of starving people on the sidewalk? How is it fair that your children get an education but the children of poor people, no matter what their reason for being poor, don't?
I think that taxation for the purpose of creating a more stable and decent society is the most fair thing we can do. The alternative is the physical manifestation of the class war that has, historically, left the rich wishing there were more fairness by the members of angry mobs.
I disagree with the greedy tone of your post and your ilk, completely. In my opinion, there are no such thing as rich children or poor children. There are just children who didn't choose to be born and certainly didn't choose their parents. Some get lucky and some get very unlucky. If your idea of "fairness" is to allow these children to starve, not have warm clothes or remain uneducated, then your concept of fairness is ass-backwards.
No, taxing those who have an abundance of luxuries to provide basic living necessities to poor people and their children is vital to maintaining an ethical society. Any society that didn't do those things would be easily said to be a plutocracy, at best, and ruled by assholes at worst.
This issue of children should be exempt from conservative/liberal debates. No political ideology that allows for that much suffering among children, to mitigate the resentment of the rich for being taxed, is a moral one, no matter what you call it. If I were a conservative, especially a christian one, I'd run from being associated with the anti-tax, anti-poor, anti-child crowd with all my might.
