War is a moral argument. Health and welfare of society is a moral argument.
As for "maximizing output", I'm failing to see big returns here. Afghanistan? Iraq? Vietnam? The only output that was maximized was cashflow to the military industrial complex.
I do believe in national security but the way we do it is not only inefficient, but manufactures more insecurity that feeds into the cycle.
My point was different: it's that some of the so-called military spending is in reality simply a way for the federal government to fund research it wants done, without any relation to actual (direct) military applications.
The sad reality is that it is easier for people to accept a massive military budget than to accept a large National Endowment for the Sciences, or to accept direct government grants for a strategy of technical development (that would be 'government interfering in the market'). Of course, this reality was created through a lot of fear-mongering propaganda, and through a lot of anti-"socialist" propaganda.
Sure, and we're discussing it via a consequence of such a case (arpanet). But because the military by default has zero accountability, any funds that go there should be strongly vetted.
