"What's the budget for the entire Catholic Church?"

Here are several answers to that question, all equally true:

• I don't know, and I doubt anyone could actually answer that question.
• Since the Church preexists creation (it has its roots in the Trinity) and is the Mystical Body of Christ, the family of the Son of the Living God, then by rights it has a claim to all things. Therefore, the created order--that's the budget of the Church.
• Since "the Church" means all of its members, the budget of the Catholic Church is equivalent to the amount of money passing into and out of the hands of all of its members at all times anywhere in the world.
• Speaking in worldly terms, I'm not sure anybody knows the amount of money passing into and out of the Church in a year for the very simple reason that we aren't Coca-Cola. There's no general headquarters with accountants tracking all the doings of all the branch offices and franchises and everything. The Pope never sees most of the money going into the collection basket every Sunday. That's simply not how it's done. It's sort of like trying to figure out what the actual budget for the "government of the United States" is for a given year, if by government we mean every single bit of those bodies which govern the United States (federal, state, county, local). Does anyone ever try to figure out that number?
