The Broken Window Fallacy

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.

Wealth has not increased, but only reallocated from some people to others, and society is worse off by one window.
