"But I also worry about the areas of the world that may see fewer donations and resulting greater hardship this year as a result of the huge, heart-warming outpouring from all over the world." When that sort of thing happens it means it wasn't really "an outpouring of generosity", it was people shifting their calculated and limited charity from one place to another, because of the headlines.

An outpouring of generosity means giving something extra, something you'd spend on yourself. And that's generally what ordinary people do, in fact, in a time like this. It's the big corporate donors, with an eye on good public relations and tax breaks, and the governments playing politics with the media, who play games by giving with one hand and paying for it by cutting back on the giving elsewhere.
