In all my life as a JW the total I contributed over a 30 year period was less than $50.00
Man, I wish I could say that about myself. In the congregation I attended, and I lived in a City close to the border of Mexico where education was nil and poverty is rampant, monthly contributions were between 5k to 10k monthly. We had many business owners in all sorts of trades making more than doctors.
We will never know how much the WT actually collects since they will NEVER print financial statements. But the point is that the WT views $ 1 dollar differently than a normal average person. Just .50 cents a week from each member would pull in more than $ 200 million dollars a year TAX FREE.
It's the advantage of the bigger you are the more advantage you have even in little things-economies of scale
