@ScanIAm: Also frees up the charity workers to do their main charitable work, rather than spending time and effort finding the money from many separate individuals.

Also ensures that minority charities get some funding too (otherwise there's a danger that the cat homes get tons of money and the clinics for the homeless get none).

I've always been happy to outsource my charitable donations to our government, if they could be trusted to actually pass it on to said charities.
