The donation system will succeed, but the financial status of the members will not. Even if people are dirt poor, they will find ways to get those pledges up. And, if they add pledges to the Worldwide Damnation Fund in addition to the building funds, it will get worse. People already have problems making ends meet and still put wads of 20's into the boxes like they are nothing. I remember seeing elderly people that were poor doing just that.
And they will pay with their souls. They will gladly surrender their souls to that beady-eyed monster joke-hova. Hardly anyone that is faithful is going to follow my rule of never donating or pledging yourself into hardship, and never pledging anything that cannot be revised in the event your financial situation gets worse. People that follow that rule, which is not endorsed by the washtowel, would avoid many of the problems created by excessive donations (and, if joke-hova owns all the wealth, that thing could create a situation where there would be a super-abundance at the end of the month, ripe for donation, and then multiply it 10, or more, times so everyone that donates bountifully would become super wealthy while providing more than ample funds for the religion).
Instead, they drain their wealth. They have zero for preparation for genuine emergencies--such as blackouts, which are all too common from storms and localized power shortages. They lack anything for personal emergencies such as car problems or medical emergencies. They cut fun to next to zero, and live on just bare necessities while donating what they pledged. They lack income because of the washtowel, and yet the washtowel takes even more. They struggle with cheap crap, and often they have personal shortages. They do not have even an ounce of silver invested, let alone enough to see them through into retirement or in case the dollar crashes and burns. Instead of preparing, they dutifully send all their wealth to the Worldwide Damnation Fund.
I say, instead of trying to coerce them to stop donating, let them face the consequences. I do advise people to not donate, but if they choose to donate anyways, it is them that will take the penalty. It is them that will retire destitute. It is them who will be programmed for poverty in the next life, and always struggle with money (and have to do a billion Jupiter and sun squares to hope to offset this). I call this the right to stupidity. You have the right to be stupid, as long as you are willing to accept the consequences. And obeying a group of men that continually drain their wealth (and time) amounts to stupidity, especially when even their "holy" texts advise only donating within one's means and not to be pleasers of men.
