Montesquieu

It is contrary to the spi­rit of com­merce for it to be car­ried on by nobi­lity in a monar­chy. “That would be dama­ging to the cities,” say empe­rors Honorius and Theodosius, “and take away the means of buying and sel­ling bet­ween mer­chants and ple­beians.”1

It is against the spi­rit of monar­chy for com­merce to be car­ried on by nobi­lity. The cus­tom that allo­wed com­merce to the nobi­lity in England is one of the things that has most contri­bu­ted to the wea­ke­ning of the monar­chi­cal govern­ment.
