A senior Walgreens executive and a Disney heir are among the ultra-wealthy Americans calling to be taxed even more to combat global inequality. 

John Driscoll, who acts as executive vice president for Walgreens Boots Alliance and is thought to have a net worth of $1.7 million, warned that the American Dream is 'rapidly diminishing' due to rising economic hardship.

He is one of 250 billionaires and millionaires supporting an initiative called Proud to Pay More which is calling on lawmakers across the world to raise levies for their country's richest. 

Driscoll joined documentary-maker Abigail Disney - the great-niece Walt Disney - in signing a new letter addressed to the world leaders gathered at the Davos summit.

Explaining his rationale for joining the campaign, he wrote: 'My grandparents emigrated to the United States from the rocky coast of southwest Ireland in the early 20th century to give their children and grandchildren a better life.

'Were it not for their dreams and hard work - my grandfather worked as a janitor and carpenter and my grandmother as a nanny - my family would not have gotten a fresh start.

'The sad truth today is that if my grandparents came to America and tried just as earnestly to get ahead, it's unlikely they would succeed - let alone lay the groundwork for their grandson to become a millionaire.'

He went on to cite a 2022 study from the Economic Policy Institute which found the average American CEO earns 399 times as much as a typical worker.

Driscoll has long been an advocate for higher wages. While CEO of home-health company CareCentrix, the company raised its minimum wage to $15 per hour.

Meanwhile Abigail Disney wrote there was a good chance readers 'recognized my surname' before adding: 'Yes, I am a member of that Disney family.'

She continued that she wanted to be levied harder to support environmentally friendly initiatives.

'We have a responsibility to ensure that our planet is healthy and habitable for future generations. 

'In my unique case as a person of wealth, I can only fulfill this responsibility if lawmakers strengthen their resolve to tax me more,' she wrote.

Other individuals to sign the letter included Citibank executive Akshay Singal and ex-Black Rock managing director Morris Pearl.
