| Abstract: | Two things make Carl Cuneo's recent (1978) paper on 'rates of exploitation' in Canada remarkable. The first is the magnitudes involved. Cuneo's preferred measure of surplus value (RSV7), for instance, shows a more than seven-fold increase from 1917 to 1971, indicating a quite spectacular shift in favour of capital in relative income shares in Canadian manufacturing industry. The second thing that makes Cuneo's paper remarkable is the extent to which his findings are inconsistent with findings on income shares reported by 'bourgeois' economists. In a survey of the literature Pen (1971: 164 ff.), for example, reports that in the advanced capitalist economies, the share of income accruing to labour in the economy as a whole has increased substantially and that even if one confines one's attention to the private sector the share of manual workers has not decreased but remained more or less constant in spite of the relative decline in their numbers.1 Now, it is true that the studies reviewed by Pen approach the problem of income shares with the categories of 'bourgeois' economics while Cuneo approaches the problem with what he regards as Marxist categories, and it is conceivable that this might have accounted for the radical difference in the findings. But still, differences of such magnitude in the trends reported in the shares of capital and labour both give pause and urge a close scrutiny. |
