Revolutionary ideas

Kohei Saito,a Japanese academic has written an analysis Of Karl Marxs latter ideas on ecology and capitalism.he expounds what he deems as eco socialism as a sustainable approach post capitalism.A groundbreaking reference he quotes from is Naomi Kleins book This Changes Everything. Now what he expounds may be in contrast or hold similar threads to Thomas Piketty Capitalism in the 21st century.but hope Saitos book is available in Japanese book shops here.Naomi Kliens book is available here but pricy.i still havent read up to a quarter of Pikettys heavy volume yet as there are complex economic.equations he uses to explain the data he garnered from historical records.
