Like you, I have much skepticism toward economics. A promising academic field became infected by arbitrary claims, slogans, false generalizations, etc. Worse, the public statements of top economists too often tend to align with the interests of rich investors, CEOs, politicians, and bankers. Therefore, I now teach a course titled “History of Money and Corruption” at UT Austin. So thank you for sharing your frank critique, especially against the religious tone of some economists’ pronouncements.
Still, it’s fair to say that at least some economists certainly try to pursue the truth. So, I’d suggest that instead of denouncing economics in general, as just “interested in establishing dogma, not pursuing truth,” you might better focus on criticizing “many economists.” Nonetheless, I agree that sometimes its helpful and important to criticize fields as a whole, so bravo for giving it a shot.
