Excellent discussion Anjali, but we haven't had capitalism for a several decades. We now have Techno-Feudalism. You are correct Capitalism exploits racial divides. The US economy was built on slavery and the subjugation of non-white and lower class whites populations at home and around the world. Now we are all digital and debt serfs. And, we will soon have an economy with little need of most of us. Mainstream economics is the great apologia for this exploitation and the making of so many humans redundant.
