Obviously one would expect the charity to report yearly on their endeavors - since no aid may be going out at all - however, reporting on each dollar would be a tad difficult to track. So not sure what would be required here.
Emptying out said donations all in one go (to avoid the perception of hoarding say all 100 billion) may not be good either since problems today may be more bearable than problems tomorrow. So not sure what would be required here either.
Probably the best remedy of those who do not wish to trust the Lds charities, would be to stop donating to them.
And the best recourse for people who spent significant sums of money donating to a charity that misrepresented their charitable actions and has acted more like a for profit business would be to initiate a class action suit for fraud and to remove the fake charity's tax exempt status.
Meanwhile, people want grand government projects to "help the middle class" but won't give Yang's UBI a shot.
The church claims that since they are a non-profit that they are therefore a charity (they have also claimed that the purpose for stockpiling $124B was for the second coming of Jesus). While they might be able to make this claim legally... it was obviously not the intention of the members who invested the money. If members intended to fund the church directly, they could have simply paid their tithing or even over-paid their tithing (as many members choose to do) as usual. But they chose specifically to donate to charity, which implies someone other than the church.
Since I am assuming you are a member, you are familiar with the tithing slip. That extra line at the bottom that says "charity:_____" yep, that money never went to charity. It went into this fund that the church kept for themselves. Very honest and Christlike.
