Well, Non, let's see if you can reason your way to the answer without speculation.
1. What was the ratio of Southern population to the North?
2. Using this ratio, and the federal spending in 1860, and what would have been a Confederate budget in the same proportion.
3. Now, take the value of Southern exports, assume a one to one ratio of import value, multiply by the tariff established in 1860, and you have your answer.
But again I will remind you that the confederate congress had passed legislation funding an army of 100,000 men that needed arms and equipment. The confederate congress had to build a navy. The confederate congress had to establish a central governmnent, a bureaucracy, a postal system, navigation system, state department and all the rest. It is reasonable to assume that the initial outlays would have been much higher than those for an established nation. So it is not unreasonable to assume that the budget requirements at first would have been much higher than those ten years down the road. A $60 million dollar budget wouldn't have been unreasonable, possibly higher. Where was the money going to come from?
