The only parts of your analysis that appears correct is that people want change and the Reagan was transformative.

The economy is only strong at the top. If you think otherwise you need to get out more.It has been 40 years since Reagan. 48 years before that was FDR.

The pendulum has swung back to where it was in the 1920s. Sanders is a true populist centrist, going against the center right establishment Democrats and the far right Republicans. His chances are very good.
