If the WT society wants to start tithing they should first encourage their members to get a good education and so get well paying jobs. tith on $10,000 is only $1,000 per year whereas tith on $100,000 is $10,000 a year also the person on $10,000 a year really cant afford to tith anyway. As they say you cant get blood out of a stone.
The SDAs tith and they also encourage higher education that seems to be a balanced approach.
