"Nobody actually feels gratitude towards things like "economies of scale" and "comparative advantage", so the only purpose of Eliezer's remark is to demonstrate his superiority over theists."
Some people, such as myself, find them aesthetically inspiring, and are happy to live in a world where they enjoy such benefits, which they did not create.
At tonight's Thanksgiving, Erin remarked on how this was her first real Thanksgiving dinner away from her family, and that it was an odd feeling to just sit down and eat without any prayer beforehand. (Yes, she's a solid atheist in no danger whatsoever, thank you for asking.)
And as she said this, it reminded me of how wrong it is to give gratitude to God for blessings that actually come from our fellow human beings putting in a great deal of work.
So I at once put my hands together and said,
"Dear Global Economy, we thank thee for thy economies of scale, thy professional specialization, and thy international networks of trade under Ricardo's Law of Comparative Advantage, without which we would all starve to death while trying to assemble the ingredients for such a dinner as this. Amen."
