"To support Imperialism by direct taxation of incomes or property would be impossible. Where any real forms of popular control existed, militarism and wars would be impossible if every citizen was made to realise their cost by payments of hard cash. Imperialism, therefore, makes everywhere for indirect taxation; not chiefly on grounds of convenience, but for purposes of concealment. Or perhaps it would be more just to say that Imperialism takes advantage of the cowardly and foolish preference which the average man everywhere exhibits for being tricked out of his contribution to the public funds, using this common folly for its own purposes. It is seldom possible for any Government, even in the stress of some grave emergency, to impose an income-tax; even a property-tax is commonly evaded in all cases of personal property, and is always unpopular. The case of England is an exception which really proves the rule."
John A. Hobson, Imperialism (1902)
