Of course, killing all the poor has been done -- in every war. The poors' housing is destroyed, their slums burnt to the ground, and the poor themselves are the conscripts who are the ones who do the fighting and get killed.
In an infamously scientific manner, Wallachian Prince Vlad Tepes (dracula) invited all the beggars in Targoviste to a banquet, during which he barred the doors and burnt the building to the ground with all the poor trapped inside it. But, to his dismay, it wasn't long before beggars could be seen on the streets again.
The big argument against Cowen is this: Thomas Edison, Alexander Graham Bell, and Guglielmo Marconi were not defense contractors or employees of the war department. They devised wonderful inventions in the interest of humanity.
The final argument against Krugman and the broken window enthusiasts is, the American economy only improved AFTER the war, some years after, to be precise, when people were finally unchained from the war machine and had to work extra hard to catch up with their lives. The British economy took a decade to improve. It took two decades for the German economy to improve, and they were still repairing the damage forty years later.
And yet, this argument still holds water with the unthinking dupes out there...
"Cowards & idiots can come along for the ride but they gotta sit in the back seat!"
