First off, Tang you focused on the income inequality portion of the article. I am not sure why people give a crap about income equality. It's irrelevant how much the top has. What matters is that the bottom is able to provide for their family.
Second, California policies, for whatever reason have led to a state of very high poverty rates. They might want to reevaluate their political beliefs as they are definitely not working.
Bernie built a platform around free education. California has this for low income earners and has indisputably the best college system in the country and yet still has all of these issues. Socialism just doesn't work.
