Economics is like astrology

Anyway, that’s a large part of what economics is—people arbitrarily, or as a matter of taste, assigning numerical values to non-numerical things. And then pretending that they haven’t just made the numbers up, which they have. Economics is like astrology in that sense, except that economics serves to justify the current power structure, and so it has a lot of fervent believers among the powerful.

This short musing amused me in Red Mars today. Also, one of those fourth wall breaking bits in a book, where the authors own opinions seem to pour out.
