Reducing daycare costs makes financial sense.  A lot of women stay home after having children and don't return to the workplace because it doesn't make financial sense to go back to work and pay $1,200+ per child per month for daycare; especially if you have more than 1 child.  That means one more person who doesn't pay income tax.  Bring daycare costs down and you'll see more women returning to the workplace, both on a part time and full time basis, which results in more income tax paid, which means more money in the government's pockets.
