Excellent rebuttal of the sturm und drang echoing in the media about the national debt.

So, to review: to make the debt look scary, you have to dismiss the post-World -War II experience, even though it turns out that the 50s offer a quite good lesson; assume that in the future the federal government will have to amortize debt over a quite short period, even though it never had to in the past; compare this inflated debt burden with a narrow piece of the federal tax base; and ignore the likely growth in the tax base over the next decade.
