Yeah, and because basically all of mainstream economics has VERY strong ideology built into its foundational assumptions, and its practitioners enjoy a great deal of (largely undeserved) respect and often great power (unlike other more truly scientific fields), the odds that a mainstream economist would look at the failure of their theories and conclude "wow, everything we've been doing is deeply flawed at best" is low. Good luck getting a mainstream economist to dig deeply and take a critical look at the fundamental contradictions within capitalism.
