The Occupy Wall Street movement, displaced from some key geographic locations, now enjoys a small but significant encampment among economists.
Concerns about the impact of growing economic inequality fit neatly into a larger critique of mainstream economic theory and its deep faith in the efficiency of markets.
Many unbelievers (including me) insist that we inhabit a global capitalist system rather than an efficient market. Willingness to use the C-word (capitalism) often signals concerns about a concentration of economic power that unfairly limits individual choices, undermines political democracy, generates financial and ecological crises and limits access to alternative economic ideas.
We can’t address these concerns effectively without a wider discussion of them.
