If I'm raising kids, then yes.
But I doubt I'm paying less taxes than you are. With a large family, I probably live in a bigger house that costs more than yours does and I probably consume more goods than you do. And then there's the taxes that my four kids will be paying as future consumers and wage-earners themselves.
So don't worry. It'll all even out in the end.
You say you should pay less taxes then try to claim you actually pay more. Sounds like a little guilt creeping in since you probably know that most Freepers and conservatives would hold to the principal of equal taxation.
Should you pay any taxes at all? If you have no income do you feel justified in receiving a check for having kids? Maybe the gov could just give you your tax credit on a debit card you know your own EBT for the EICTC. No need to file just give you the card to present at a grocery store.
If you are eligible for any part of this welfare payment then I can assure you that I pay far more taxes than you do. Hint: Do the EITC phase out math.
