This has not shown to be the case as we have seen with American artillery shell production. The companies are not yet ramping up, because they don't want the ground cut out from under them if the war ends early next year and congress decides to cut any funding.
Turns out having fickle, lazy, stupid, feckless politicians have the ability to destroy projects with the stroke of a pen on a whim after every election means nobody is willing to put up their own investment, and having a business sector that is largely run by shithead middle management types who have never worked a day in their lives that wasn't just balancing a spreadsheet are unwilling to do something because it doesn't promise a HIGH ENOUGH return on investment.

God forbid you don't make ALL the profit.
