A funny statement on Wikipedia about church finances is:
Whatever the actual figure [of assets], about two-thirds of it is made up of non-income-producing facilities and the land they sit on, including thousands of meetinghouses ...
The meetinghouses are non-income-producing assets? How do you figure that? Let's see, when I was a finance clerk, we collected about $38,000 a month in a humble ward. That means our ward, plus the ward that shared the building that generated about $912,000 annually.
That means every Sunday when we opened the doors of our non-asset-producing building (48 weeks removing 4 Sundays for General- and Stake Conferences), the "take" was about $19,000 tax- and accountability free ca$h!
To be fair, the church building was just the collection point. The money collected was ransom so they could see their families again and go to the temple.
Factories don't produce income either. Neither do buildings that house banks. Apartment buildings don't produce income. In fact, I can't think of a single building type that produces income. People produce income by supplying goods and services to other people. It sounds like Gordo Hinkley wrote that article.
