Does destruction create jobs? After natural disasters, terrorist attacks, and wars, some people argue that these disasters are good for the economy, because they create jobs and prosperity. When a shopkeeper’s window is broken, he will spend money on a new window, which gives income and jobs for glaziers. This activity is “seen,” but the “unseen” is just as important: the money spent on a new window could have been spent on other things. Wealth has not increased, but only reallocated from some people to others, and society is worse off by one window.
