The broken window fallacy revolves around the argument that destruction is economically beneficial. The reasoning behind this is that a destructive act will create jobs as someone will be hired to fix the problem.1
The name of this fallacy comes from the original example of a boy breaking a shopkeepers window. The onlookers try to put a positive spin on the situation. "This event must be positive overall, as without such acts of window breaking the glazier down the road would be out of business!".
