If duties are too high, they lessen the consumption; the collection is eluded; and the product to the treasury is not so great as when they are confined within proper and moderate bounds. This forms a complete barrier against any material oppression of the citizens by taxes of this class, and is itself a natural limitation of the power of imposing them.

As to Taxes, they are evidently inseparable from Government. It is impossible without them to pay the debts of the nation, to protect it from foreign danger, or to secure individuals from lawless violence and rapine.

There is perhaps, nothing more likely to disturb the tranquillity of nations, than their being bound to mutual contributions for any common object that does not yield an equal and coincident benefit. For it is an observation as true, as it is trite, that there is nothing men differ so readily about as the payment of money.

It is a singular advantage of taxes on articles of consumption that they contain in their own nature a security against excess. They prescribe their own limit, which cannot be exceeded without defeating the end purposed - that is, an extension of the revenue.
