Unregulated capitalism is not what's causing the massive inequality we see today. It's the financial and monetary policies. I'm not saying we shouldn't have regulations but the ones we have are centralizing wealth into the biggest corporations. If you look this modern massive growth of inequality doesn't really start until the 1970's after we whet off the gold standard and theirs an uptick in inequality every time the fed decides it needs to pump a bunch of money into the economy.
