Congressional report finds higher tax rates don't hurt growth, so Republican party has it pulled

"Changes in the top marginal tax rate do not appear correlated with growth."

A new report from the US's Congressional Research Service has been suppressed by Republicans after it concluded that tax rates are uncorrelated with economic growth or saving, investment, and productivity growth – but do affect the extent of income inequality in the nation.

The report concludes:

The top income tax rates have changed considerably since the end of World War II. Throughout the late-1940s and 1950s, the top marginal tax rate was typically above 90%; today it is 35%. Additionally, the top capital gains tax rate was 25% in the 1950s and 1960s, 35% in the 1970s; today it is 15%. The average tax rate faced by the top 0.01% of taxpayers was above 40% until the mid-1980s; today it is below 25%. Tax rates affecting taxpayers at the top of the income distribution are currently at their lowest levels since the end of the second World War.

The results of the analysis suggest that changes over the past 65 years in the top marginal tax rate and the top capital gains tax rate do not appear correlated with economic growth. The reduction in the top tax rates appears to be uncorrelated with saving, investment, and productivity growth. The top tax rates appear to have little or no relation to the size of the economic pie.

However, the top tax rate reductions appear to be associated with the increasing concentration of income at the top of the income distribution. As measured by IRS data, the share of income accruing to the top 0.1% of U.S. families increased from 4.2% in 1945 to 12.3% by 2007 before falling to 9.2% due to the 2007-2009 recession. At the same time, the average tax rate paid by the top 0.1% fell from over 50% in 1945 to about 25% in 2009. Tax policy could have a relation to how the economic pie is sliced—lower top tax rates may be associated with greater income disparities.

The report is particularly important for its treatment of capital gains tax as well as just income tax. The former is significantly lower than the latter, and has been for all but three years of the US's post-WWII history. As a result, it is a significant avenue for tax avoidance.

The argument for keeping capital gains tax low is that it stimulates investment, by encouraging people to invest rather than spend income. If, as the report concludes, it is in fact unconnected with investment rates, then that method of tax-dodging could be closed without harming the economy much, if at all.

The report, which was written by a neutral government body, was not welcomed by the Republican party, which is opposed to much taxation. The New York Times' Jonathan Weisman writes:

Senate Republican aides said they had protested both the tone of the report and its findings. Aides to Mr. McConnell presented a bill of particulars to the research service that included objections to the use of the term “Bush tax cuts” and the report’s reference to “tax cuts for the rich,” which Republicans contended was politically freighted.

They also protested on economic grounds, saying that the author, Thomas L. Hungerford, was looking for a macroeconomic response to tax cuts within the first year of the policy change without sufficiently taking into account the time lag of economic policies. Further, they complained that his analysis had not taken into account other policies affecting growth, such as the Federal Reserve’s decisions on interest rates.

“There were a lot of problems with the report from a real, legitimate economic analysis perspective,” said Antonia Ferrier, a spokeswoman for the Senate Finance Committee’s Republicans. “We relayed them to C.R.S. It was a good discussion. We have a good, constructive relationship with them. Then it was pulled.”

Leader: Boris Johnson, a liar and a charlatan

The Foreign Secretary demeans a great office of state with his carelessness and posturing. 

Boris Johnson is a liar, a charlatan and a narcissist. In 1988, when he was a reporter at the Times, he fabricated a quotation from his godfather, an eminent historian, which duly appeared in a news story on the front page. He was sacked. (We might pause here to acknowledge the advantage to a young journalist of having a godfather whose opinions were deemed worthy of appearing in a national newspaper.) Three decades later, his character has not improved.

On 17 September, Mr Johnson wrote a lengthy, hyperbolic article for the Daily Telegraph laying out his “vision” for Brexit – in terms calculated to provoke and undermine the Prime Minister (who was scheduled to give a speech on Brexit in Florence, Italy, as we went to press). Extracts of his “article”, which reads more like a speech, appeared while a terror suspect was on the loose and the country’s threat level was at “critical”, leading the Scottish Conservative leader, Ruth Davidson, to remark: “On the day of a terror attack where Britons were maimed, just hours after the threat level is raised, our only thoughts should be on service.”

Three other facets of this story are noteworthy. First, the article was published alongside other pieces echoing and praising its conclusions, indicating that the Telegraph is now operating as a subsidiary of the Johnson for PM campaign. Second, Theresa May did not respond by immediately sacking her disloyal Foreign Secretary – a measure of how much the botched election campaign has weakened her authority. Finally, it is remarkable that Mr Johnson’s article repeated the most egregious – and most effective – lie of the EU referendum campaign. “Once we have settled our accounts, we will take back control of roughly £350m per week,” the Foreign Secretary claimed. “It would be a fine thing, as many of us have pointed out, if a lot of that money went on the NHS.”

This was the promise of Brexit laid out by the official Vote Leave team: we send £350m to Brussels, and after leaving the EU, that money can be spent on public services. Yet the £350m figure includes the rebate secured by Margaret Thatcher – so just under a third of the sum never leaves the country. Also, any plausible deal will involve paying significant amounts to the EU budget in return for continued participation in science and security agreements. To continue to invoke this figure is shameless. That is not a partisan sentiment: the head of the UK Statistics Authority, Sir David Norgrove, denounced Mr Johnson’s “clear misuse of official statistics”.

In the days that followed, the chief strategist of Vote Leave, Dominic Cummings – who, as Simon Heffer writes in this week's New Statesman, is widely suspected of involvement in Mr Johnson’s article – added his voice. Brexit was a “shambles” so far, he claimed, because of the ineptitude of the civil service and the government’s decision to invoke Article 50 before outlining its own detailed demands.

There is a fine Yiddish word to describe this – chutzpah. Mr Johnson, like all the other senior members of Vote Leave in parliament, voted to trigger Article 50 in March. If he and his allies had concerns about this process, the time to speak up was then.

It has been clear for some time that Mr Johnson has no ideological attachment to Brexit. (During the referendum campaign, he wrote articles arguing both the Leave and Remain case, before deciding which one to publish – in the Telegraph, naturally.) However, every day brings fresh evidence that he and his allies are not interested in the tough, detailed negotiations required for such an epic undertaking. They will brush aside any concerns about our readiness for such a huge challenge by insisting that Brexit would be a success if only they were in charge of it.

This is unlikely. Constant reports emerge of how lightly Mr Johnson treats his current role. At a summit aiming to tackle the grotesque humanitarian crisis in Yemen, he is said to have astounded diplomats by joking: “With friends like these, who needs Yemenis?” The Foreign Secretary demeans a great office of state with his carelessness and posturing. By extension, he demeans our politics.
