You are the last person on FR anyone should ever look to for basic economic theory. And, there is more than one economic theory on most any subject. That's why there are many schools of economic thought. (I could predict your response)
And what many are discussing here is not economic theory, but what the desired outcomes of the US economy should be. Of course, you'd be unable to consider such matters as how the economy and national security might be related, being as straightjacketed by your chosen pet theories as your obviously are.
