Great-Britain's true system [electronic resource] : wherein is clearly shown, I. that an increase of the public debts and taxes must, in a few years, prove the ruin of the monied, the trading, and the landed interests : II. the necessity of raising the supplies to carry on war, within the year : III. that such a design, however seemingly difficult, is very practicable, with a sketch of various schemes for that purpose : IV. an expedient which will support the public credit, in all times of public distress and danger : to which is prefixed, an introduction, relative to the forming a new plan of British politicks, with respect to our foreign affairs, and our connections on the continent : humbly submitted to the consideration of all the great men, in and out of power / by Malachy Postlethwayt.
