"We have been living in an ideological bubble — one of market fundamentalism.From the trauma of the Great Depression to 1973, there was a broad consensus across the democratic world that markets were absolutely essential to generate wealth, but they will also cause all sorts of problems if they are left unregulated. Economists like JM Keynes and JK Galbraith taught us that if you abolish markets, you get starvation; but if you abolish all the democratic checks and balances on markets, you get a system that eats itself. Unregulated businesses will cause unsustainable levels of pollution and inequality, and ultimately start pursuing unhinged business models that cause the whole system to collapse."
