The Fallacy of the Broken Window is generally correct, but ...
It assumes monetary velocity is a constant. If velocity has collapsed, then breaking windows can create wealth because it circulates money throughout the economy. It can also be beneficial when there is excess capacity in the economy.
Also, it can be very good for your economy if you are breaking other people's windows. This is why war spending can be stimulative.
As well, the OP has made a mistake implying that the broken window theory and stimulus are the same thing. They are not.
This may be what they teach in economics but it is dead wrong. It takes away more than it stimulates. If a 30 year window still had 15 years of good service life remaining & it was destroyed then we lost. That money spent to replace that window was pulled from the bakers investments that was leveraged 4 to 1 creating jobs. Now 4 new higher level jobs are not created & an established window installer makes a few bucks. A new 30 year window will be placed in the series of remaining windows that will all be replaced again in 15 years. Also broken windows lead to lost business. Customers, surrounding business & community feels less secure & relocate to safer communities. Broken windows lead to increased crime, fewer jobs & lost opportunities. Study -

Also the shop owner & the surrounding community becomes somewhat depressed after an incident. Depressed people do not stimulate the economy. They stop spending & begin nesting. Just look at what happened to the economy after 9/11. The Fed had to over stimulate a housing bubble to get the economy to start moving again.
