There is an implied contract, much stronger than any instrument or article of agreement between the labourer in any occupation and his employer—that the labour, so far as that labour is concerned, shall be sufficient to pay to the employer a profit on his capital, and a compensation for his risk; in a word, that the labour shall produce an advantage equal to the payment. Whatever is above that, is a direct TAX; and if the amount of that tax be left to the will and pleasure of another, it is an ARBITRARY TAX.
