"This society in which knowledge workers dominate is in danger of a new "class conflict" between the large minority of knowledge workers and the majority of workers who will make their livings through traditional ways, either by manual work... or by service work. The productivity of knowledge work - still abysmally low - will predictably become the economic challenge of the knowledge society. On it will depend the ability of the knowledge society to give decent incomes, and with them dignity and status, to non knowledge people."
