That's correct, but again, that's compared with what the current tax law is. The cost to the treasury is relative to what the current tax law is. The current tax law is that you pay the taxes according to your income, but under the family tax cut, you can have that exemption or the tax savings by making that allocation. Whatever you do would be a cost to treasury relative to the amount of money the treasury would have gained from that income.
