Davenant, like an able politician, who had the state of facts before him, reasoned according to actual circumstances. Whatever was borrowed on long funds, was charged on the standing revenue of the state, which parliament was very unwilling to increase in proportion to the charges laid upon it. This, of itself, was argument sufficient with him to cast his view upon short appropriations, or upon his favourite object, of raising money within the year, to supply the exigencies of the state.
But in this operation he found great difficulties. In his treatise of ways and means, article excises, where he is searching for expedients to provide money for the war, he plainly shews a thorough knowledge of that imposition. It had taken place in England as far back as the great civil war, and formed at the revolution about ⅓ of all the revenue: but what is very extraordinary, and which at present will hardly be credited, the excise had at that time the effect of sinking the price of the subject excised, instead of raising the price of what was produced from it. Thus the excise upon malt, after the revolution, had the effect of lowering the price of barley, instead of raising the price of beer.
This effect of excises Davenant saw; from which he, and since him many more have concluded, that all excises fall ultimately upon the land.
This circumstance, together with a feeling for the interest of the great number of idle poor at that time, who must constantly suffer by excises, engaged Davenant to propose having recourse to the land-property and poll-taxes, for raising, within the year, the sums required for carrying on the war.
According to his proposal, there was to be no less than 3 millions raised by a land tax, besides half a million by a quarterly poll, which was, at that time, above 100,000l. more than all the permanent taxes of England put together.
A proposal of this kind coming from Davenant, shews the difference of situation between those times and the present. On this subject more is to be learned by comparing facts, than by all the reasoning in the world.
We have seen how credit stood in England during the reign of William III. It was then in its infancy, and was set upon the principles of a free and limited authority, exercised by ministers of state at all times responsible to parliament at the risk of their heads, in case of any open violation of the public faith. This is the best of all securities against the bad exercise of power.
Whoever reads the admirable writings of Davenant, and compares his ideas with what experience has since taught us, concerning the nature of taxes and public credit, will plainly discover that the great distress of England at that time, proceeded from the following causes.
The enterprize they were engaged in, was far beyond their power to support, although they had the greatest part of Europe to assist them.
The bravery of the British nation was ill supported with money, the sinews of war.
