The Borg is putting greater emphasis on young persons. Young guys are being appointed as MS earlier. Now that there is no 10 hour minimum in FS being tracked by FS reports, it will be even easier to promote less zealous young guys. At MS/Elder meetings when the CO comes through, contributing is a focus. I recall it being said that this group alone (MS/Elders) should be contributing enough to carry the expenses and any thing from others was "gravy".
That really makes an impression on young MS who is striving to be promoted to Elder.
I am not sure, but I suspect that with the new online donation arrangement, they know how much you are giving. I know for a fact that they know if you cancel your monthly tithe and will call to check on your "spirituality".
