The Open Society and Its Enemies (Princeton Classics)

by Karl Popper

The amended theory of surplus population and of the trade cycle may be outlined as follows. The accumulation of capital means that the capitalist spends part of his profits on new machinery; this may also be expressed by saying that only a part of his real profits consists in goods for consumption, while part of it consists in machines. These machines, in turn, may be intended either for the expansion of industry, for new factories, etc., or they may be intended for intensifying production by increasing the productivity of labour in the existing industries. The former kind of machinery makes possible an increase of employment, the latter kind has the effect of making workers superfluous, of ‘setting the workers at liberty’ as this process was called in Marx’s day. (Nowadays it is sometimes called ‘technological unemployment’.)
