TAXES AND MIGRATION. Remember the old saying, "when all you have is a hammer, every problem looks like a nail?" Well, as Mark Steyn shows, when all you know is tax cuts, every problem stems from high marginal rates. He genuinely appears to think that illegal immigrants enjoy their status: After all, no taxes! It's "the perfect arrangement for modern life ." That you have to hide in the bushes every time your employer decides payroll is too high and the INS should come by the plant for a look-see is, I'd guess, a small price to pay for the much-heralded grail of federal tax relief. --Ezra Klein
