Tactical mistakes and a blowtorch of establishment opposition to her supply-side tax cuts forced Liz Truss to resign as British prime minister last fall after only six weeks in office.

But Truss has formed a new group to go up against what she calls the “anti-growth caucus” in both the U.S. and Britain. In her Margaret Thatcher lecture at the Heritage Foundation last week, she gave her audience a sense of how much her thinking tracks with that of Thatcher.

She assailed “wokeism” and “political correctness,” deplored French president Emmanuel Macron’s call for Europe to seek “strategic autonomy” from the U.S., identified the forces strangling the economy of both her country and ours, and called for conservatives to coordinate across the Atlantic.

Truss lamented that the legal, educational, and environmental establishments are united in resisting changes in the status quo. “There are people who work in businesses that invoice the government and they’re doing quite fine, thank you very much,” Truss said. “As prime minister, I simply underestimated the scale and depth of this resistance and the scale and depth to which it reached into the media and into the broader establishment.”

She lamented that both the International Monetary Fund and President Biden himself coordinated opposition to her tax cuts. “It’s not a matter for the U.S. president, it’s a matter for the U.K. government how we best have tax rates that deliver for everybody across our country,” she thundered. She then took a swipe at Biden’s subsidy-stuffed “Inflation Reduction Act” by saying it would “encourage U.S. industry to spend their time rent-seeking.”

Truss finished by saying that the U.S. and Britain must expand ties and promote free trade. She contrasted that with Biden’s call for an international tax cartel that sets a minimum corporation tax rate across all countries. She dismissed it by saying: “We need a U.K.-U.S. trade deal, not a U.K.-U.S. tax deal.”

It’s indeed unfortunate that Truss left office so suddenly, as she has a lot of the grit that Margaret Thatcher had, but we have no doubt that she will continue to contribute to shaping the debate in Britain — especially if the Labor Party wins the next election — and the Conservative Party returns to its roots.
