I read your post, Attlee wasn't making a point, he was telling us one of his fundamental beliefs any person who wants a decent society should believe in. it's nothing to do with sexier causes, it's about rich people paying their taxes so poor people don't have to rely on charity to survive, it's about rich people dodging taxes should not consider themselves decent people just because they toss a few bob at charity when they are in a good mood.
The last word we should be using for rich tax dodgers is Philanthropy, people who pay their taxes and give to charities are philanthropists.
Well you might have read what I said, but...oh, hell, forget it, this is not the place for this discussion, and I doubt this will go anywhere good.
For my part, I just hope everyone who is charitable continues being charitable, regardless of their level of wealth, and that those who generally aren't, are inspired by the example of those who are, even if the inspirational ones are rich. There's so much, so much, so much that needs to be done in the world. So many people in need and also non-person charities that need help. Personally, I couldn't give a stuff if some rich blob swaggers around largeing it and does it for the accolade, provided the money still ends up with those who need it.
And for the avoidance of doubt I also, of course, expect everyone to pay their taxes, fully and without evasionary tactics. I also [insert some aspirational guff about some sexy chick or ones idealised paramour].
