Adam Smiths's four principles of taxation taken from the Wealth of Nations
"The rich should contribute to the public expense not only in proportion to their
revenue," Smith believed, "but something more than in that proportion."
"the tax which each individual is bound to pay ought to be certain and not arbitrary" and
"clear and plain"--that is, transparent to everyone.
"ought to be levied at the time, or in the manner, in which it is most convenient for the
contributor to pay it."
"both to take out and keep out of the pockets of the people as little as possible over and
above what it brings into the public treasury of a state."
Using Adam Smith's four principles of taxation above evaluate the local sales tax
system based on each criteria.

Scenario 1
Two men live alone on an isolated island. To survive they must undertake a few basic
economic activities like water carrying, fishing, cooking and shelter construction and
maintenance. The first man is young, strong, and educated. He is also faster, better, and
more productive at everything. He has an absolute advantage in all activities. The
second man is old, weak, and uneducated. He has an absolute disadvantage in all
economic activities. In some activities the difference between the two is great; in others
it is small.
Based on Scenario 1 above critically evaluate the following statement. "Because of
the productivity differential between the two men we can conclude that the young man
has a comparative advantage in the production of everything over the older man.
