Normal People get to think they are helping 3$'s worth, and Rich people get to think they are helping 3$'s worth...
Both side get to feel like they got more out of the initial investment.
1:3 2:3
Everyone wins inside their heads and its nice to live life where everyone wins...
Also easier to justify charity when you think you are winning..
I feel like it's pretty good for what it is.
Actually rich people think they re helping more than that. If we assume the average length of a recurring donation is 6 months they feel they help 8 dollars for every 2 they donate.
But otherwise you are right, this is done because it makes everyone donating feel like a winner other than few cynics like me. :D But that said I do not mind these drives.
