Color me unconvinced, too. He brings up the example of the income tax as why the slippery slope argument fails, but it's actually a pretty convincing case study of the merits of the slippery slope argument. The income tax was originally pushed through in 1894 with the argument that a small income tax (only on the very richest, of course) would allow for tariff reductions. Several years later, tariffs were increased again with no corresponding decrease in the income tax. When the sixteenth amendment was being debated, arguments were made for a clause that would limit the tax to at most 10% of income, but the clause was abandoned because no one thought the income tax could or should get that high.
