“It seems almost in bad taste to talk about dollars and cents after an act of mass murder
“The most immediate consequence was a halt to the campaigns of the Hundred Years’ War. In the long term, the decrease in population caused a shortage of labour, with subsequent rise in wages, resisted by the landowners, which caused deep resentment among the lower classes. The Peasants’ Revolt of 1381 was largely a result of this resentment, and even though the rebellion was suppressed, in the long term serfdom was ended in England. The Black Death also affected artistic and cultural efforts, and may have helped advance the use of the vernacular.”

Unless you were one of those killed. Kind of an ultimate "broken window."
Also, the Black Death is an interesting case in that ALL productive assets and capital goods remained in tact. Nothing at all was destroyed - only people.
