The assertion does not have support in literature. While the Austrian school contends that increased debt produces diminishing growth over time, there is no basis for the revised equation that removes government spending from the calculation.
If we eliminate the "G" in the equation, then we suppose that government ceases to exist. That includes the military. Is this your position?
Huh? If I don't include fried peanut butter and banana sandwiches in the equation, does that mean they don't exist? No, just that Elvis' gastro-pleasures don't add to the strength of the economy. You pick the military to try to make it sound like I don't care about our troops so as to interject emotion into the argument. Just like your strawman and ad hominem arguments, it is the refuge of those without a leg to stand on. However, even your supposed point, taking wealth created by the private sector to support a military doesn't add to the economy, because, and I will try to use small words, government (sorry, that one has three syllables) does not create wealth, it takes it.
