I agree with the analysis and the solution pathways that I have chosen to engage in deeply is education and with it both liberation and empathy. The populist movement comes from a population that feels something like abandoned.
The white working class were always told that if they worked hard they too could be rich and they will always be better then those other guys. And then everything changed. This populist movement is absolutely about stolen dreams and it is also about racial caste. This is what our police forces are protecting. This is what #BLM and the Dreamers are describing in clear and righteous tones. Economics is not about money, it’s about well being. The behavioral economists have taught us that we make decisions based on social capital and well being, not GDP.
None of this is counter to your analysis. Hopefully it is complementary.
