Why would anyone who attends a meeting and donates think they own anything? People who contribute are just donors and those doing ministry, volunteers, like with other charities. If I donate to and volunteer for my local homeless shelter I have no right to think I own part of the homeless shelter.
Local congs (at least in the UK) have in their charitable objectives the furtherance of the worldwide work, so its perfectly reasonable for a local branch or a national branch to pass the money up the line if it can be better deployed elsewhere where there is a greater need
do people who donate to oxfam in Edinburgh think their donations should only be used in Edinburgh?
