^{Page 571 note 1} With respect to skilled labour, Lewis contends that ‘it is theoretically possible that the immigration of skilled workers may reduce the demand for the services of native unskilled workers, but this is most unlikely. More probably it will make possible new investments and industries which were not possible before, and will thus increase the demand for all kinds of labour, relatively to its supply.’ Ibid. p. 436.
