I liked this formulation from the blog The Coming Prosperity, posted today as a link on Twitter:
If solutions are known, need $$. If solutions are knowable, need evaluations. If solutions are evolving, need entrepreneurs.
Consumer Warnings: This comes at the end of a long diatribe against You-Know-Who (associated with $$). I'm not sure the author is a reliable guide to other people's work, since Yours Truly is incorrectly associated with "evaluations." But I still like the 3 sentences above.
