More than any other time in history, mankind faces a crossroads. One path leads to despair and utter hopelessness. The other, to total extinction. Let us pray we have the wisdom to choose correctly."

In Frédéric Bastiat's parable, a shopkeeper has a window broken by his son and is obliged to pay, say, six francs to fix it. 
Some onlookers reason that breaking windows is a good thing, since it causes money to circulate - in this case, into the hands of a grateful glazier. But Bastiat points out that since the shopkeeper has had to spend six francs on getting his window repaired, he has been deprived from spending the money on anything else.

Consider, alternatively, the fates of Japan and Germany at the end of the Second World War. The economies of both defeated powers were shattered. Japan and Germany as nations may have lost the war, but their economies won the peace. Japan rapidly modernized into a robust industrial economy. Ditto Germany, which enjoyed what 'The Times' in 1950 called a Wirtschaftswunder, an economic miracle, as it emerged from the ashes. This has led some strategists to suggest, not entirely facetiously, that it would be in the best interests of an ailing industrial economy - Britain's, say - to have its factories and economic infrastructure routinely and totally destroyed, every so often.
There is another, more recent, application of a theory involving broken windows. An article entitled “Broken Windows” was published in „The Atlantic Monthly? in 1982. Consider, it posited, a building with a few broken windows. If those windows are left unrepaired for any length of time, there will be a tendency for vandals to break some more. The downtrend may lead to the building?s being occupied, or torched. The article became a book, and its author, George Kelling, became a consultant to the New York City Transit Authority in 1985, which duly implemented the theory. Kelling went on to work with the LAPD and the Boston Police Department. New York City Mayor Rudy Guiliani and his police commissioner Howard Safir are also credited with using a similar “broken windows” / zero tolerance approach to urban crime, which caused both petty…
