Last week the Trump administration and its congressional allies working on tax reform achieved something remarkable. They released a tax plan — or, actually, a vague sketch of a plan — that manages both to add trillions to the deficit and to raise taxes on a large fraction of the population. That takes talent.

But like the G.O.P.’s terrible, no good, very bad health plans, this tax debacle was years in the making. On taxes, as with health, leading Republicans have been lying for years. And now the fraud has caught up with the fraudsters.

The road to this tax-cut turkey began in 2010, when Paul Ryan — now speaker of the House — unveiled the first of a series of much-hyped budget plans, all purporting to offer a blueprint for eliminating the U.S. budget deficit.

In fact, they did no such thing. They proposed major tax cuts — primarily benefiting the rich, of course — then simply asserted that no revenue would be lost, because reduced tax rates would be offset by closing loopholes and eliminating deductions. Which loopholes and deductions? Ryan didn’t say.
