Polly Cleveland — Piketty’s Model of Inequality and Growth in Historical Context, Pt 2

Neoclassical economics was designed for the purpose of eliminating economic rent from consideration.
Mason Gaffney has shown how many individuals helped construct neoclassical economics, often with financial support from the robber barons and their successors. I will focus on two: in the United States, John Bates Clark (1847-1938), and in Europe, Vilfredo Pareto (1848 to 1923). 
Recall from Part I that the classical economists divided society into three classes: Owners of land and other natural resources received unearned income or “rent” from their holdings—often derived from conquest or inheritance. Capitalists (who often overlapped with landowners) owned physical capital (like factories or ships) and received interest or profit from investing. Workers received wages. Also recall that the classical economists favored taxing “rent” by taxing land values; Henry George crusaded for this tax. 
John Bates Clark of Columbia University, for whom is named the prestigious John Bates Clark Medal, transformed economics into an inequality-free abstraction.Writing in the 1890’s, Clark merged land into physical capital, thus obliterating the classical understanding of land. In the new neoclassical world, capital (including land) originates solely from productive investment. There is no unearned “rent”, only legitimate “profit.” (Ironically, Marx merged rent into profit because he considered both illegitimate.)
Power rules.
In my view, Piketty’s and Solow’s models are both fundamentally flawed in that they rest on the same ahistorical, apolitical, two-factor neoclassical foundation. As the classical economists understood, inequality derives from power, ultimately the power of conquerors to extract tribute from the conquered. And as the Progressives, the New Dealers, and the civil rights activists have demonstrated, democratic societies can counter that power with well-designed tax and regulatory policies supported by an aroused public. We are not prisoners of a mathematical model.

For some reason, I'm reminded of Socrates' famous phrase: "After thunder comes rain".

"And as the Progressives, the New Dealers, and the civil rights activists have demonstrated, democratic societies can counter that power with well-designed tax and regulatory policies supported by an aroused public."

Didn't Piketty recommend... tax increases, exactly like Cleveland does? So, what was all the thundering about?

The same bucket of cold water poured on Socrates' head.
