Pay

With the development of the productive powers of labour the accumulation of capital will be accelerated, even despite a relatively high rate of wages. Hence, one might infer, as Adam Smith, in whose days modern industry was still in its infancy, did infer, that the accelerated accumulation of capital must turn the balance in favour of the working man, by securing a growing demand for his labour. From this same standpoint many contemporary writers have wondered that English capital having grown in that last twenty years so much quicker than English population, wages should not have been more enhanced.
