While I consider those to be worthy goals too, I'm afraid you won't find any realistic financing for that: Rich people are egotistic and merciless, while considerate and idealistic people never get rich. I too think we should spread, for obvious reasons (eggs and baskets come to mind, never mind that bad habit of gnawing at your own basket).

Indeed. And in the century after that either. Humans don't really change, we're still the same uncouth cavemen we once were, we've only learned to occasionally wash... :-D
