The highest ordinary rate of profit may be such as, in the price of the greater part of commodities, eats up the whole of what should go to the rent of the land, and leaves only what is sufficient to pay the labour of preparing and bringing them to market, according to the lowest rate at which labour can anywhere be paid, the bare subsistence of the labourer. The workman must always have been fed in some way or other while he was about the work, but the landlord may not always have been paid. The profits of the trade which the servants of the East India Company carry on in Bengal may not, perhaps, be very far from this rate. The proportion which the usual market rate of interest ought to bear to the ordinary rate of clear profit, necessarily varies as profit rises or falls. Double interest is in Great Britain reckoned what the merchants call a good, moderate, reasonable profit; terms which, I apprehend, mean no more than a common and usual profit. In a country where the ordinary rate of clear profit is eight or ten per cent. it may be reasonable that one half of it should go to interest, wherever business is carried on with borrowed money. The stock is at the risk of the borrower, who, as it were, insures it to the lender; and four or five per cent. may, in the greater part of trades, be both a sufficient profit upon the risk of this insurance, and a sufficient recompence for the trouble of employing the stock. But the proportion between interest and clear profit might not be the same in countries where the ordinary rate of profit was either a good deal lower, or a good deal higher. If it were a good deal lower, one half of it, perhaps, could not be afforded for interest; and more might be afforded if it were a good deal higher. In countries which are fast advancing to riches, the low rate of profit may, in the price of many commodities, compensate the high wages of labour, and enable those countries to sell as cheap as their less thriving neighbours, among whom the wages of labour may be lower.
