Back to reading Stalin, which I would like to complete by the end of February. This on one grain as the currency of currencies, in the midst the intensified class struggle with the kulaks:

Grain should not be regarded as an ordinary commodity. Grain is not like cotton, which cannot be eaten and which cannot be sold to everybody. Unlike cotton, grain, under our present conditions, is a commodity which everybody will take and without which it is impossible to exist. The kulak takes this into account and holds back his grain, infecting the grain holders in general by his example. The kulak knows that grain is the currency of currencies (Works, vol 12, p. 93).
