22.16. 16. The Assistance a State may derive from Bankers.
The banker's business is to change, not to lend, money. If the prince makes use of
them to change his specie, as he never does it but in great affairs, the
least profit he can give for the remittance becomes considerable; and if
they demand large profits, we may be certain that there is a fault in
the administration. On the contrary, when they are employed to advance
specie, their art consists in procuring the greatest profit for the use
of it, without being liable to be charged with usury.
