While wages have flatlined for most working-class people, rents have reached new highs, leaving most people struggling. But it's not just in the US. The rising cost of living has affected the entire world. Samuel Stein's new book, Capital City and the Real Estate State, highlights the growing influence of investment capital into land as the driving force behind gentrification and the power developers have over city and local governments. We talk to Samuel about the rise of the global real estate market and we look at how radical city planning, rent control and socialized land projects can help fight gentrification.
