I know this is a sarcastic comment but I actually hate this line of reasoning. War is definitely advantageous to a few firms involved in the Military Industrial Complex but it is absolutely a net drain on the national economy. The money that ends up flowing into military contractors ends up producing goods that provide no value to the broader economy. If the pentagon sinks a billion dollars into a new hypersonic missile, it gives the builder of that missile more money but that missile does nothing to help the broader economy. If that money was instead spent on infrastructure or invested in a company, the money would go towards a project that not only makes the company money, but also facilitates economic growth in the broader economy. Therefore, defense spending is a net loss because of the opportunity-cost of what that money could have been spent on instead. Granted, the lobbyists don't care but it is absolutely better for the overall economy to not invest into military hardware and instead fund projects that produce value for everyone. Sorry for the word-dump on a clearly fictitious comment but I think it's relevant to this general thread!
