Who’s huffing and puffing? I just pointed out that having a slim budget is not related to their wealth, and they do have billions of dollar.
And I say "What's it to you?"
Why do you care? What are you implying? How much do you think the Vatican should be allowed to have? Who would you like to decide how much is too much?
This "wealth" that attracts your weird obsessive interest serves to fund the Holy See's world-wide religious, charitable, and cultural responsibilities. You may think none of this is important -- but that would only mark you as a person of limited understanding and imagination. Believe me, it would be missed. Their endowment is less than the Ford Foundation's. Start yelling about them for a change and lay off the Catholic-bashing.
