London has become the super-rich capital of the world, ranking in the top 5 cities with the most billionaires… with the result that it also has the highest cost of living in the world.There is a human cost to this affluence. Working people can barely afford to live in the city, and the vibrant culture that attracted so many in the first place is destroyed as the rich buy up property and push up rents and prices.Will these changes choke off the flow of ideas and innovation that has made London into one of the world’s great cities? Or will they help create a thriving global metropolis for the 21st century?Journalist and broadcaster Miranda Sawyer will be joined by prospective London mayoral candidate David Lammy MP, cultural commentator Peter York, co-author of The Sloane Ranger Handbook, and Mira Bar-Hillel, property correspondent for the London Evening Standard, to debate if money is making London… or ruining it.
