The progressive-liberal values are America's values, and we need to go back to them. The heart of progressive-liberal values is simple: empathy (caring about and for people) and responsibility (acting responsibly on that empathy). These values translate into a simple principle: Use the common wealth for the common good to better all our lives. In short, promoting the common good is the central role of government.
