This analysis of Bernie Sanders’s economic plan by Gerald Friedman at University of Massachussetts-Amherst has made quite a splash, suggesting it could lead to massive improvements in economic growth, unemployment, inequality, and productivity, all while investing heavily for the future in infrastructure, education, and climate change readiness. Bill Moyers.com has a long roundup of the criticism and support from all sides, finally concluding that it is actually plausible using standard, even conservative principles of economics. To me, even if it is only partially true, it just shows how unbelievably badly our economy has been managed over the past few decades, and how unready for the future we actually are.

Meanwhile, the Trump economic plan just doesn’t remotely add up using any known principles of arithmetic.
