thegreatfatsby asks: Do you think the fact that Gabriel Zucman, who is a recognised authority on wealth tax is given more respect, time and attention by the mainstream media than Gary Stevenson, who has worked eloquently and tirelessly to spread the debate about the terrible consequences of inequality and whose ideas and analysis are almost identical is because of our cultural fixation on class prejudice?

Aditya says: I’ve followed Gabriel Zucman (and Emmanuel Saez and Thomas Piketty) for a long time, and find his work rigorous and thought provoking. I don’t always agree, but I appreciate their acceptance that taxes on wealth are part of the fight against ever-increasing inequality.

I think Gary Stevenson is eloquent and compelling and is fighting a good fight. His book tells a story very well. But I don’t accept the insistence on a ‘wealth tax’ (as opposed to taxes on wealth) as being the only way we fight everything from inequality to the far right. We have to look at workers’ rights, housing, public ownership, greater democracy in economics and politics as well.

In the age of algorithm, simple, strong messages cut through. But the truth is often more complex.

Aditya says: What a nice question, Marija. I try to read a lot and write a diary. Unfortunately, I have the handwriting of a GP so I can’t read old entries. The other thing is I try to shirk my mobile phone.

IOPC launches independent investigation after referral by Scotland Yard over 2019 letter about Thomas Markle

Scotland Yard faces an independent investigation into its failure in 2019 to pass claims alleging wrongdoing by Thomas Markle, the father of the Duchess of Sussex, to law enforcement agencies overseas.

The force had referred itself to the Independent Office for Police Conduct (IOPC) over its handling of a letter written by Markle’s former wife, Roslyn Loveless. Markle, 82, is now facing claims of child sexual abuse in the Philippines, which he denies, and is under investigation by authorities there.

The president cancelled the events in favor of tele-rallies, as Republicans face a fight to retain control of Congress

Donald Trump cancelled, and then promptly uncancelled, two in-person rallies in Kansas and Iowa this weekend as polls suggest US midterm election races in the previous Republican strongholds could go down to the wire.

On Thursday, just five days before election day, the Republican National Committee (RNC) announced the president would no longer host the Kansas and Iowa rallies and instead participate in “a large number of tele-rallies”. The RNC claimed it felt it was in a “strong position” in Kansas and Iowa.

Business is booming for two biggest US oil companies, with both benefiting from higher prices and record production

ExxonMobil and Chevron both reported better than expected quarterly results on Friday as the oil majors benefited from higher prices and record production.

The boon for oil companies has simultaneously been a major pain point for consumers, who say the higher cost of living, especially gas prices, will affect how they vote in the upcoming midterm elections that will determine control of Congress.

Fragments of personal objects, from makeup tools and a perfume bottle to coins and a child’s necklace, have been found tucked away in a wooden wardrobe sealed off for almost 2,000 years in the ruins of Pompeii.

The artifacts provide an intimate glimpse of daily life in the ancient Roman city before it was devastated by the eruption of Mount Vesuvius in AD79. The wardrobe was discovered in a room of a home on Via dell’Abbondanza, which was one of the most bustling streets in Pompeii.

• Alaska Senate race: what to know about Democrats’ alleged ballot-stacking effort

Mary Peltola has denied that she knew anything about an effort to put another candidate on the Alaska ballot with the same name as the Republican incumbent, as the US justice department escalated a criminal investigation this week with new grand jury subpoenas.

“I just want to clear the air,” the Democratic Senate candidate said on Thursday at the top of a speech in a downtown bar in Juneau, Alaska’s capital. “I knew nothing about any other candidate on the ballot except for me and the incumbent. That is all I have ever known about. I am not interested in tricking voters.”

The Swedish climate academic Andreas Malm has condemned a travel ban imposed on him by the UK government as a “drift into authoritarianism” amid criticism of the move.

Street protests sweeping Europe are expected to spread to Germany and reignite in France on Saturday, with police mobilised to stop potential looting and rioting on the fringes of what organisers hope will be peaceful rallies.

Pike is facing death penalty for 1995 murder of classmate, despite surviving a botched execution last month

Christa Pike has marked a month since her failed execution by Tennessee and released a statement in which she laments the “incompetence” that has led to this moment, adding that despite ongoing healing she remains in constant physical pain and mental anguish.

In comments released by her legal team on Friday, the prisoner said that there had not been a moment since she was injected with a massive dose of the sedative pentobarbital that she had not been in pain. “My body hurts. My arms hurt. My hands hurt. My throat hurts. I still struggle to speak. And the pain isn’t just physical. There is pain in my mind and in my soul,” she said.

• Europe live – latest updates

Spain’s prime minister, Pedro Sánchez, has admitted “trust in high-speed rail has been broken” after Wednesday’s train collision that killed at least 69 people, injured more than 100 and prompted a national debate on the safety of the country’s rail network.

Sánchez said Spain was “working tirelessly” to provide information as quickly as possible to the families of the victims – who include people from at least 23 different foreign countries – adding his government was committed to finding what had caused the country’s second deadly train collision this year.

Brazilian media ridicule defeated candidate over ‘shameful’ absconsion to US and bizarre letter with wrong coat of arms

Flávio Bolsonaro had hoped that by Sunday night people would be calling him the next president of Brazil.

Instead, the far-right politician’s decision to flee to the US after losing the election and – for 58 minutes – to declare himself “Brazil’s true president-elect”, has made him a laughing stock, with Brazilian newspapers and commentators raining a barrage of scornful adjectives down on the conquered candidate.

Altering copyright law to allow AI companies to scrape music, books and journalism could trigger a constitutional breach, Coalition senators and the recording industry have warned, as they raise new fears it could open Australia to massive legal action and compensation claims from rights holders worldwide.

The attorney general’s department admitted it was “extremely alive” to the issue, and Australia’s leading constitutional expert, Anne Twomey, agreed there was “potentially” a concern – depending how legislation was drafted – that granting AI companies permission to scrape copyrighted material from the internet could amount to an acquisition of property by the government.

Vega said she still doesn’t know why she was fired from the show, which has experienced a slump in ratings.

Cecilia Vega, the 60 Minutes correspondent fired as part of a dramatic overhaul of the CBS News show this spring, said it “hurts” to see what has happened to the storied newsmagazine and other segments of the network, and repeated allegations that she was told to insert “factually untrue” information into her work.

“It pains me. It hurts to watch, from afar. It hurts to talk to my colleagues who are still there. It hurts to see the ratings slump that is happening right now,” Vega said during a Thursday evening talk for students at American University in Washington DC.

Andrea Egan calls for same political focus on teachers, care sector and NHS and says Jackdaw decision ‘a serious misstep’

• UK politics live – latest updates

The leader of the UK’s biggest trade union has called for the same political focus to be given to NHS, education and care sector workers as there has been on those employed in North Sea oil and gas.

Andrea Egan, the general secretary of Unison, said too often public sector workers were treated as an “afterthought” by the government compared with the “massive political focus” on protecting jobs in the North Sea.

Young dancers at the Ivy House in south-east London join the older crowd amid a renewed appetite for authentic, community events

The Ivy House pub in Nunhead, south-east London, has long been associated with raucous music, with the rock legends Ian Dury and Elvis Costello gracing its stage in the 70s, and indie favourites caroline and Kiran Leonard pulling in crowds today. But last Friday, it was a traditional Scottish ceilidh dance rather than a grassroots gig luring London’s cool kids to its sticky dancefloor.

The event is emblematic of a renewed appetite for analogue, in-person experiences among a younger generation plagued by a loneliness epidemic and fatigued by meeting people on dating apps.

Simon Richardson, 35, crashed into headteacher Michael Mullins, 56, who was cycling home from work at Stretford grammar school, Greater Manchester, on the evening of 20 April. Mullins hit the bonnet and windscreen of Richardson’s Volvo XC90 and then went under the car, becoming entangled in the suspension.

Lawyers for the former FBI director James Comey will ask a federal judge on Friday to block the US justice department from pursuing its third criminal case against him.
