John Ross — Deng Xiaoping - the world's greatest economist

China’s economic performance after the beginning of its 1978 reforms simply exceeded the experience of any other country in human history. To give only a partial list…

But while in one sense Deng Xiaoping "returned to Marx," he necessarily had to resolve many problems of a modern economy Marx never envisaged. Purely theoretically, a number of these had been analyzed by Keynes in the 1930s. Keynes’ fundamental conclusion was that investment played the determining role in the economy, "the fluctuations of output… depend almost entirely on the amount of current investment" (Keynes conclusion has since been comprehensively confirmed by statistics). As, in a modern economy, investment is financed by borrowing, Keynes advocated very low interest rates to incentivize investment. But Keynes judged these alone would be insufficient to stably maintain an adequate investment level. 

It was therefore necessary for the state to play a direct role in setting the level of investment: "I am… skeptical of the success of a merely monetary policy directed towards influencing the rate of interest… I expect to see the state… taking an ever greater responsibility for directly organizing investment." Keynes noted: "I conclude that the duty of ordering the current volume of investment cannot safely be left in private hands."

But if the "the current volume of investment" were to be set, Keynes realized this meant a large state investment role: "I conceive… that a somewhat comprehensive socialization of investment will prove the only means of securing an approximation to full employment."
Keynes noted such a "somewhat comprehensive socialization of investment" did not mean eliminating the private sector, but socialized state investment operating together with a private sector: "This need not exclude all manner of compromises and devices by which public authority will co-operate with private initiative… The central controls necessary to ensure full employment will, of course, involve a large extension of the traditional functions of government." Keynes, consequently, envisaged an economy in which a private sector existed but in which the state sector was sufficiently dominant to set overall investment levels.

But Keynes’ analysis remained purely theoretical. It could not be implemented in the West for an insurmountable reason – which is why the West’s "Keynesianism" bears little relation to Keynes’ own writings! Capital investment is "the means of production." If the most basic investment decisions were not taken by private capital, it would no longer be a capitalist society. Keynes had developed an incisive theoretical analysis, but which could not be implemented in the society in which he lived.

Problems which were insurmountable for Keynes were, however, no problem for Deng Xiaoping – as he did not intend to create a capitalist society! To be clear, there is no evidence Deng Xiaoping’s economic concepts were directly influenced by Keynes. But ideas Deng Xiaoping was entirely familiar with from Marx led to the same economic structure as Keynes. The state would retain ownership of large scale (i.e. socialized) economic sectors, thereby giving it the ability to regulate the investment level, while smaller scale economic sectors (non-socialized production) could be released to the private or non-state sector. The state therefore did not need to own the overall economy, just to own enough to set the overall investment level.
