The WTS finances are just fine and there is nothing to worry about. There have been changes to some magazines and tracts are being used for upcoming conventions. However, the cost of renting the convention centers is very high and they are having two or three conventions in many areas.
The JW's have 1 million baptized members in the US and another 1.5 million that are not baptized that attend congregations and support the WTS. They also are growing overseas and are financing legal battles in foreign countries regarding their beliefs and practices.
If the average congregate gives $50 per month that is $125,000,000 per month and $1,500,000,000 per year.
I thought there were 93K congs or so worldwide, right? So, 93,000 * $50 = $4,650,000 monthly or $55,800,000 yearly. Either way you sound like a sympathizer and of that figure I wonder how many got DF'd last year, or just plain faded. If you look at there "growth" statistically you will see it is stagnant at best...
