Sasha Volokh argues that it isn’t.
I think that’s because money is downright weird: sometimes, to get enough of it to get things done, you need to have a bunch of it–as if you were picking bits of playdough up off of the kitchen table with a large glob of play dough. And sometimes, you need a complete absence of it–as if you were getting the vacuum cleaner out to whoosh! up all those bits of capital.
That’s my new economic theory; it may not be ready for prime time.
