Mark Thomas is founder of the 99% organisation (https://99-percent.org/)
He is also the author of 99%: Mass Impoverishment and How We Can End It (an FT Best Book, 2019).

While running the Strategy Practice at PA Consulting Group, he used the tools of business strategy to help understand the health and stability of countries. He found that many developed countries are pursuing economic policies which will result in the unwinding of 20th century civilisation before the year 2050. Hearteningly, he also concluded that this fate is avoidable.
