[T]here should be a heavily progressive National inheritance tax on big fortunes. The really big fortune, by the mere fact of its size, acquires qualities which differentiate it in kind as well as in degree from what is possessed by men of relatively small means. A heavily progressive inheritance tax on all such fortunes (heaviest on absentees) has the good qualities of an income tax, without its drawbacks; it is far more beneficial to the community at large, and far less burdensome to private individuals, as well as far more easily collected. A moderate, but progressive, income tax, carefully devised to fall genuinely on those who ought to pay, would, I believe, he a good thing; but a heavy and heavily progressive inheritance tax on great fortunes would be a far better thing.
