We’ve got to be able to have fair, reasonable ways to tax the super wealthy without demonizing them.
The wealthy pay a lot, however, due to how incredibly much they have, and inequality, they still don’t pay their fair share. The goal of taxation is to pay for government in the least harmful way possible, not to liquidate the rich. Fair taxation and reasonable welfare policy is good. Class warfare is evil. A society that taxes in order to end billionaires, or that uses rhetoric that endangers the wealthy, will be a violent and repressive society–either because the masses will turn authoritarian and violent, or because the wealthy will out of fear.
