Matt Lauer was publicly roasted last week after he failed to hold Donald Trump to account during the "Commander in Chief Candidates Forum", but Lauer isn't the only media personality - or "news person," whatever that means these days - who needs to step up his game and press guests to tell the truth.

We shouldn't just be demanding tougher treatment of presidential debate candidates.

We should be demanding that interviewers in the media start calling out so-called "experts" when the experts are caught distorting the truth.

Earlier this morning for example, Morning Joe hosted one of Donald Trump's informal economic advisors, Larry Kudlow, who revealed this shocking revelation about who really was the first president to use "supply side economics", also known as trickledown "Reaganomics"

There's just one major, glaring problem with Kudlow's analysis.

It's not true.

John F. Kennedy didn't invent trickle-down Reaganomics, and his policies had nothing to do with trickle-down Reaganomics.

Kudlow wasn't entirely wrong when he said that Kennedy suggested we should cut marginal income taxes rates, Kennedy's plan cut the lowest earners' taxes from 20 percent to 14 percent, and it cut the highest earners' taxes from 91% to 65%.

But the Kennedy tax code also closed a series of loopholes and tax exceptions, so the overall effect was that the government took in more tax revenue than before the "cuts"

It was, in other words, a tax hike.

And he made it explicitly clear during his third debate against Richard Nixon that his changes to the tax code would increase tax revenue, the definition of a tax increase, and wouldn't be offset by gutting government spending.

So why is Larry Kudlow out peddling this bogus notion that John F. Kennedy, a Democrat, actually invented supply side economics?

It's probably because the early 60s was pretty much the only time in 20th century American history that cutting the top tax rate has coincided with an increase in real economic growth.

As Mehrun Etebari pointed out back in 2003 at www.faireconomy.org, there are at least four simple pieces of evidence that show that trickle-down economics doesn't work.

During the half-century period between 1954 and 2003, Etebari notes that "Overall, there seems to be no close relationship between the top tax rate and the GDP growth rate, and statistical analysis backs this up."

During that same 50-year period, there was also no relationship between tax cuts and median household income either.

Etebari writes that "Once again, the lack of connection between [top tax rates and household median income] is backed up by a correlation coefficient of near zero. [�] And yes, yet again, the coefficient is positive, indicating that income has gone up slightly (though negligibly) more in years with higher taxes."

He also shows that there are no connections between top tax rates and hourly wages or job creation, and he sums up that "[A]ny attempt to stimulate economic growth by cutting taxes for the rich will do nothing, it hasn't worked over the past 50 years, so why would it work in the future?"

But cutting tax rates for rich people does have one consistent and predictable outcome, the rich get a lot richer and working people get the shaft. The past 40+ years of Reaganomics have proven that year after year.

Unfortunately, harsh historical realities aren't going to stop think tanks like the Cato Institute and FreedomWorks from manufacturing research for pseudo-economists like Larry Kudlow and Art Laffer to peddle, on mainstream corporate outlets like CNN, Fox so-called News, or the allegedly liberal MSNBC.

And harsh historical realities aren't going to stop Kudlow from trying to give credence to the terrible failure of trickle-down Reaganomics by blaming John F. Kennedy.

In reality, Kennedy shaped his policies based on Keynesian economics, which is in direct opposition to the Libertarian Milton Friedman school of so-called "free market" economics that's promoted "trickle-down" Reaganomics for over 50 years.

But people who watched Kudlow's segment on Morning Joe wouldn't know that because reporters don't challenge hucksters like Larry Kudlow on TV anymore.

When the hosts of Morning Joe don't push back against Kudlow's fantasies, the viewers may never learn that Kudlow is wrong, just like when Matt Lauer refuses to push back against Trump for lying about his position on the Iraq War.

Matt Lauer's moderation left a lot to be desired during the Commander In Chief candidates forum last week, but it wasn't any worse than what goes on day in and day out during interviews on any of the corporate 24-hour news networks.

It's time that the media start challenging so-called "experts" like Larry Kudlow, especially when the expert is simply trying to re-write American history to tell a story that fits within his or her own billionaire-funded ideology.
