How did Bill Gates become the richest man in America? His wealth has nothing to do with Microsoft producing good software at lower prices than its competitors, or ‘exploiting’ its workers more successfully (Microsoft pays its intellectual workers a relatively high salary). Millions of people still buy Microsoft software because Microsoft has imposed itself as an almost universal standard, practically monopolising the field, as one embodiment of what Marx called the ‘general intellect’, by which he meant collective knowledge in all its forms, from science to practical know how. Gates effectively privatised part of the general intellect and became rich by appropriating the rent that followed.-Slavoj Zizek, "The Revolt of the Salaried Bourgeoisie"
The possibility of the privatisation of the general intellect was something Marx never envisaged in his writings about capitalism (largely because he overlooked its social dimension). Yet this is at the core of today’s struggles over intellectual property: as the role of the general intellect – based on collective knowledge and social co-operation – increases in post-industrial capitalism, so wealth accumulates out of all proportion to the labour expended in its production. The result is not, as Marx seems to have expected, the self-dissolution of capitalism, but the gradual transformation of the profit generated by the exploitation of labour into rent appropriated through the privatisation of knowledge.
