from the Cato Policy Report, Deirdre McCloskey writes How Piketty Misses the Point:

What caused the Great Enrichment? It cannot be explained by the accumulation of capital, as the very name “capitalism” implies. Our riches were not made by piling brick upon brick, bachelor’s degree upon bachelor’s degree, bank balance upon bank balance, but by piling idea upon idea. The bricks, BAs, and bank balances were of course necessary. Oxygen is necessary for a fire. But it would be unenlightening to explain the Chicago Fire of 1871 by the presence of oxygen in the earth’s atmosphere.

The original and sustaining causes of the modern world were indeed ethical, not material. They were the widening adoption of two new ideas: the liberal economic idea of liberty for ordinary people and the democratic social idea of dignity for them. This, in turn, released human creativity from its ancient trammels. Radically creative destruction piled up ideas, such as the railways creatively destroying walking and the stage coaches, or electricity creatively destroying kerosene lighting and the hand washing of clothes, or universities creatively destroying literary ignorance and low productivity in agriculture. The Great Enrichment requires not accumulation of capital or the exploitation of workers but what I call the Bourgeois Deal. In the historical lottery the idea of an equalizing liberty and dignity was the winning ticket, and the bourgeoisie held it.

That even over the long run there remain some poor people does not mean the system is not working for the poor, so long as their condition is continuing to improve, as it is, and so long as the percentage of the des-perately poor is heading toward zero, as it is. That people still sometimes die in hospitals does not mean that medicine is to be replaced by witch doctors, so long as death rates are falling and so long as the death rate would not fall under the care of the witch doctors. It is a brave book Thomas Piketty has written. But it is mistaken.
