Over the course of this week we'll be hearing a lot about Ronald Reagan, much of it false. A number of news sources have already proclaimed Mr. Reagan the most popular president of modern times. In fact, though Mr. Reagan was very popular in 1984 and 1985, he spent the latter part of his presidency under the shadow of the Iran-Contra scandal. Bill Clinton had a slightly higher average Gallup approval rating, and a much higher rating during his last two years in office.

We're also sure to hear that Mr. Reagan presided over an unmatched economic boom. Again, not true: the economy grew slightly faster under President Clinton, and, according to Congressional Budget Office estimates, the after-tax income of a typical family, adjusted for inflation, rose more than twice as much from 1992 to 2000 as it did from 1980 to 1988.

But Ronald Reagan does hold a special place in the annals of tax policy, and not just as the patron saint of tax cuts. To his credit, he was more pragmatic and responsible than that; he followed his huge 1981 tax cut with two large tax increases. In fact, no peacetime president has raised taxes so much on so many people. This is not a criticism: the tale of those increases tells you a lot about what was right with President Reagan's leadership, and what's wrong with the leadership of George W. Bush.

The first Reagan tax increase came in 1982. By then it was clear that the budget projections used to justify the 1981 tax cut were wildly optimistic. In response, Mr. Reagan agreed to a sharp rollback of corporate tax cuts, and a smaller rollback of individual income tax cuts. Over all, the 1982 tax increase undid about a third of the 1981 cut; as a share of G.D.P., the increase was substantially larger than Mr. Clinton's 1993 tax increase.

The contrast with President Bush is obvious. President Reagan, confronted with evidence that his tax cuts were fiscally irresponsible, changed course. President Bush, confronted with similar evidence, has pushed for even more tax cuts.
