- Increasing taxes
- Decrease spending in other areas
- Increasing the debt
If you're not convinced yet, imagine that instead of dropping bombs on Baghdad, the army was dropping refrigerators in the ocean. The army could get the refrigerators in one of two ways:
- They could get every American to give them $50 to pay for the fridges.
- The army could come to your house and take your fridge.
As far as the second one, do you think you'd feel wealthier if the army came and took your appliances away from you? The idea of the government coming in and taking your things may seem ridiculous, but it's not any different than increasing your taxes. At least under this plan you get to use the stuff for awhile, whereas with the extra taxes, you have to pay them before you have an opportunity to spend the money.
So in the short run the war will hurt the economy of the United States and their allies. It goes without saying that flattening most of Iraq to rubble will decimate the economy of that country. Hawks are hoping that by ridding Iraq of Saddam, a democratic pro-business leader can come in and improve the economy of that country in the long run. The economy of the United States could improve in the long run due to the war for a couple of reasons:
- An increased supply of oil
Depending on who you ask, the war either has everything to do with Iraq's vast oil supplies, or absolutely nothing to do with it. All sides should agree that if a regime with better American relations were set up in Iraq, the supply of oil to the United States would increase. This will drive down the price of oil, as well as driving down the costs of companies that use oil as a factor of production which will certainly help economic growth. - Stability and Economic Growth in the Middle East If peace can somehow be established in the Middle East, the U.S. government might not have to spend as much money on the military as they do now. If the economies of the countries in the middle east become more stable and experience growth, this will give them more opportunities to trade with the United States, improving both the economies of those countries and the U.S.
