As a counter-example, let me point to Notre Dame, where the first day's $339 million has now swelled to a billion dollars. Even by Washington, D.C. standards, that's serious money. No government shook them down for it; the Pope isn't handing out extra next-life goodies to the donors.
If a big project is sufficiently important to enough people, it will be funded.
* * *An interesting aside to this is, who owns that famous building? Nope, it's not the Catholic Church -- it's the very secular French government! But the Church occupies it rent-free and maintains and staffs the place. This is perhaps another example of "the French do things their own way," and much like French engineering, it works for them even if it's not how you'd expect it to be set up.
In a larger (and more figurative) sense, Notre Dame belongs to the world, in much the same way as the Taj Mahal or the Empire State Building. And that's how "the world," everyone from business moguls to academic institutions to schoolkids, responded to the fire damage.
