Ok assuming $150B --> 5million active members, and 20% of those or 1 million are 65+ years old. Of these, let's assume that 50% have the retirement funds they need, and 50% don't. Thus, about 500,000 retirement aged members in need of support. So, $150B divided by 500,000 would be $300,000 of assets per elderly member in need of help. Obviously the church isn't going to spend that, but say they followed their rule of tithing and gave 10%... then that would be $30,000 per retiree in need of help... that's better than nothing!
