Throwing money at them only goes so far and there are already people doing that. This will create employment, like the Public Works Admistraion did in America during the great depression.
Exactly, just in the same way the cathedrals were built in the first place… to keep the masses busy and gainfully employed. What better way than to take a few hundred years to build a cathedral employing several generations of peasants, giving them useful skills, to keep them in check, give them jobs in a society before law and order, religion served as an effective mechanism to create some moral and societal structure and rule based living all with the ever present threat of some all powerful, all seeing, all knowing beardy bloke floating up above the clouds who would condemn you to an eternity of torment and pain in the pits of hell if you step out of line. Religion is a man-made construct created for practical purposes to serve the progress of mankind. It should have been superseded when the rule of law was invented and our current civic structures started to emerge, but so much power in the hands of a few blokes in gowns and silly hats was too much to relinquish and so we still have to suffer the scourge of religion.
Despite my opinion on religion I am in awe of the buildings and structures it created, or rather the skills and workmanship of the people Who created them, and these things are worth preserving and rebuilding. I love Paris and it would be all the poorer if they don’t rebuild it.
