Taxing

I am doing my taxes tonight. The thing I always wonder is, why do I only get to claim $5K tax exempt for childcare when I spend so much more than that? Would I be able to work at all without childcare? Why can't I deduct all of the amount I spend on childcare? If it weren't for childcare, I wouldn't be contributing to the economy. Anyway, I am up way too late but I really want to get this done now because I can't endure another session of this. Happy Friday! Oh, wait, it's Saturday! (I hope everyone sleeps in.)
