Yesterday Trump embraced torture, despite its long standing reputation of failure.
Today Trump went all-in for supply-side economics by appointing its most dedicated disciple - Larry Kudlow.

What kind of economic policies would the general public embrace? Large majorities want to see the rich pay higher taxes -- exactly the opposite of what Kudlow wants. Infrastructure investment is popular too, as are minimum wage hikes and a variety of antipoverty programs.

Kudlow is on record for predicting that Trump's tax cuts will pay for themselves, a position that literally no economists agrees with.

"I think this thing is going to pan out better than almost anybody thinks. The deficit is going to be much lower," Kudlow said. "This thing is going to pay for itself."

To be fair to Kudlow, being wrong about the economy is sort of "his thing".
First of all, Kudlow is a one-trick pony.

The purest supply-siders, like Kudlow, go further and deeper in their commitment. Kudlow attributes every positive economic indicator to lower taxes, and every piece of negative news to higher taxes. While that sounds absurd, it is the consistent theme he has maintained throughout his career as a prognosticator. It’s not even a complex form of kookery, if you recognize the pattern. It’s a very simple and blunt kind of kookery.

So when you have someone pretending to be a serious economist, that also adheres to a failed economic theory like a priest in a dying religion, the results are predictable.

In 1993, when Bill Clinton proposed an increase in the top tax rate from 31 percent to 39.6 percent, Kudlow wrote, “There is no question that President Clinton’s across-the-board tax increases … will throw a wet blanket over the recovery and depress the economy’s long-run potential to grow.” This was wrong. Instead, a boom ensued. Rather than question his analysis, Kudlow switched to crediting the results to the great tax-cutter, Ronald Reagan.
...He began to insist that the housing bubble that was forming was a hallucination imagined by Bush’s liberal critics who refused to appreciate the magic of the Bush boom. He made this case over and over (“There’s no recession coming. The pessimistas were wrong. It’s not going to happen. At a bare minimum, we are looking at Goldilocks 2.0. (And that’s a minimum). Goldilocks is alive and well. The Bush boom is alive and well.”) and over (“The Media Are Missing the Housing Bottom,” he wrote in July 2008). All of this was wrong. It was historically, massively wrong.
When Obama took office, Kudlow was detecting an “inflationary bubble.” That was wrong. He warned in 2009 that the administration “is waging war on investors. He’s waging war against businesses. He’s waging war against bondholders. These are very bad things.” That was also wrong, and when the recovery proceeded, by 2011, he credited the Bush tax cuts for the recovery. (Kudlow, April 2011: “March unemployment rate drop proof lower taxes work.”) By 2012, Kudlow found new grounds to test out his theories: Kansas, where he advised Republican governor Sam Brownback to implement a sweeping tax-cut plan that would produce faster growth. This was wrong. Alas, Brownback’s program has proven a comprehensive failure, falling short of all its promises and leaving the state in fiscal turmoil.

Basically, Kudlow is to economics what neocons are to foreign policy.
He is always and forever wrong about everything, while completely unable to acknowledge his failures.
Basically he's perfect for a Trump White house.
