I hope they implement this. Its a wonderful idea to wake up a lot of JWs. I do not see this going anywhere good for the society. All the JWs I know, would do anything for the org except part with their money. Its theirs. They are the least generous of religious groups I have encountered. The society has done it to their own detriment. They encourage service above being a generous decent human, so they have killed off any generosity in that, "we do service thats life saving". My peer group 30/40s NO WAY would give a set amount of money-- if so it would be a ONE time thing. Not monthly.
If they said birthdays and thanksgiving were okay and reversed some ridiculous policies against innocuous birthdays and the like, THEN I could see potentially giving of their income.
