I agree we can do a lot better. And I have no moral qualms about giving the excess away to everyone who needs it. But I need people to admit that it will require a lot of work till we can sufficiently claim we have a real realizable "excess".
And that work requires the current system to work more "efficiently" and with "higher productivity", in the economic definition of the word, not as a personal valuation as OP defines.
