Hume's basic problem with public debt is that it has no limit, at least until the interest rates on the debt become crushing. Plus, debt is easy to levy since its costs are hidden and intergenerational, which makes states love debt. As Hume put it, "it is very tempting to a minister to employ such an expedient, as it enables him to make a great figure during his administration, without overburdening the people with taxes. … The practice will, therefore … almost infallibly be abused, in every government." Accordingly, government will issue debt at a rate that shall exceed the rate of interest that it could earn elsewhere, therefore finding ready buyers at the cost of diverting funds from industry. As a consequence, capital will become concentrated in debt securities that "banish gold and silver from the commerce of the state … and by that means render all provisions and labour dearer than otherwise they would be."
