For RDean....

.....an interesting view supporting an early form of unequal or graduated
taxation:
"When the toll upon carriages of luxury, upon coaches, postchaises, &c. is
made somewhat higher in proportion to their weight, than upon carriages of
necessary use, such as carts and wagons, &c. the indolence and vanity of the
rich is made to contribute in a very easy manner to the relief of the poor."

want to guess the source of the quote?
