> The real cure for a sluggish economy is a large-scale, man-fought war (barring any kind of nuclear event). War simultaneously boosts demand as the government ramps up spend across a bevy of sectors (industrial, aerospace, medical, food, science, tech) and the labor force decreases for obvious reasons.

The government spends as much as they can on all those things because people believe their very existence is at stake. Too bad we can't find that sense of urgency any other way.
