The man of great wealth owes a peculiar obligation to the State, because he derives special advantages from the mere existence of government. Not only should he recognize this obligation in the way he leads his daily life and in the way he earns and spends his money, but it should also be recognized by the way in which he pays for the protection the State gives him.
 Theodore Roosevelt, State of the Union Address. copy citation

Context

“In addition to these there is every reason why, when next our system of taxation is revised, the National Government should impose a graduated inheritance tax, and, if possible, a graduated income tax. The man of great wealth owes a peculiar obligation to the State, because he derives special advantages from the mere existence of government. Not only should he recognize this obligation in the way he leads his daily life and in the way he earns and spends his money, but it should also be recognized by the way in which he pays for the protection the State gives him. On the one hand, it is desirable that he should assume his full and proper share of the burden of taxation; on the other hand, it is quite as necessary that in this kind of taxation, where the men who vote the tax pay but little of it, there should be clear recognition of the danger of inaugurating any such system save in a spirit of entire justice and moderation.” source
