Except for the fact that they probably don't pay much in taxes at all since they get $15000/yr. in tax credit for their kids.
It's not that I disagree with the policy or anything, but the tax burden in the country is shifted heavily towards people with few or no kids.
The people paying the most eggregious share are thoese working single people who don't live in a house yet. Ouch!
I believe that's a deduction instead of a credit but I agree with the main point of your reply.
Three of my four adult children are married with children of their own and pay very little in taxes compared to what my wife and I pay. My one son is in the same boat - married but with no kids. He pays through the nose too.
