Conversation so far:
What did Unger critique about econimics?
Unger's critique of economics begins with the identification of a key moment in economic history, when the analysis of production and exchange turned away from social theory.
how did he identify this key moment?
In Unger's analysis, classical economics focused on the causal relations among social activities, which were connected with the production and distribution of wealth.
