It's a combination of many factors... those building cost a lot more than people think......and the "donation" system is more "freewill" than "pledges"
The Average JW hears phrases like "non-profit" and then gets a little "widows mite" theology in the same day he gets a little confused. Then they bad bad mouth churches for having structured 'donations'. Go figure, the average JW figures that his $2 bucks or whatever will go a long way.
Running a building for anyones orginization costs bucks. If you joined a conservation and shooting club you would be asked for membership dues.. and any guests would pay for services rendered.. why? Land, equipment, taxes insurance costs all must be met... and at years end after all is paid out not much remains in the pot. Even though the board or the voting members dont take a "profit" you have to pull in more than you spend on legit costs of business.
In my opinion there would not be anything wrong with asking for "pledges"... it would save many problems.... and it's a lot less tacky than the guilt ridden pan-handling the poor Accounts servant has to do to meet monthly expenses.
Then, Brooklyn gets their cut... everymonth...... before they got so rabid about a regular cut a congregation would often carry a reserve...
The average JW doesnt see the "Kingdom Hall" in that light. He is convienced "God" will take care of things. Plus many JW's are on a tight budget at home... then MANY JW's are just plain CHEAP. Or figure the family with the new Suburban or nicer house has TONS of cash and will carry the ball.
I really got tired of panhandling the electric bill every month while I was on accounts 20 years ago... I can't imagine how that job goes now... Glad I am out.
