1. It destroys stuff, which then needs to be rebuilt creating jobs.
2. It kills lots of people which lowers the unemployment rate since fewer people alive means more jobs for those still left alive.
1. Destroy stuff — there are 10 houses, they are destroyed. 1 year later there are 10 houses, but you’ve lost x years of man labor and materials to get back to where you started from. PURE WASTE. If you want to hire people, just have the G hire the unemployed to move a sand pile from here to there and back again.
Dead people — If people die, then there are fewer people to make things which = less productivity. True, there are fewer people demanding things, but that is simpy a wash at best. Among the dead are certainly people who were far more productive than infants. Of course loss of one’s life is the loss of an economic good, even more hurtful than the loss of one’s Cadillac.
