a "war chest" is usually saved by the state (by under-investing into everything civilian) and then given back to the working-class population as salaries, sign-up bonuses, investment into logistic infrastructure. If you look up the stats - there was a real-estate boom in the early years of the was as many families could finally take a mortgage. Now many cannot pay for it because the bonuses and soldier salaries "don't last" hence companies like "Samolyot" are now in trouble.
