Trump showed that the annihilation of the American middle class was not the result of inevitable forces.
Technological change and globalization are not weather or the movement of tectonic plates.
The economy, and who gets what from whom, is embedded in political choices.
Who pays the costs and who reaps the benefits are political choices.
Who is crushed by the legal system and who benefits from it, and who is insulated from it, are also political choices.
Trump will never be forgiven for showing normal people that their destruction, and the enrichment of other people, who despise everything that they love, believe in, and care about, is a policy decision.
Trump showed other choices are possible.
Having seen once how it actually works, we can never unsee it.
That is Trump’s greatest achievement.
