87. Money employed in cultivation, manufactures, or commerce,
ought to produce more than the interest of money on loan.
By a like reason, money employed in agriculture, in
manufactures, or in commerce, ought to produce a more
considerable profit than the revenue of the same capital employed
in the purchase of lands, or the interest of money on loan: for
these undertakings, besides the capital advanced, requiring much
care and labour, and if they were not more lucrative, it would be
much better to secure an equal revenue, which might be enjoyed
without labour. It is necessary then, that, besides the interest
of the capital, the undertaker should draw every year a profit to
recompence him for his care, his labour, his talents, the risque
he runs, and to replace the wear and tear of that portion of his
capital which he is obliged to invest in effects capable of
receiving injury, and exposed to all kinds of accidents.
