I do understand that talking points require certain inflammatory statements be intoned. That said, your depiction of "class warfare" - that of the teeming multitudes against the very wealthy - takes partisan rhetoric into mendacity.
"Class warfare" is Bill Gates explaining - from his vast mountains of riches and nil teaching experience - how having thirty students in a class wouldn't make much of a difference.
"Class warfare" is Republican-dominated state legislatures condemning the formerly pensioned to penury while protecting and increasing their own lifetime rewards.
"Class warfare" is the rising poverty rate nationwide.
"Class warfare" is the end of the free snack Food Bank program at many school sites this year, because fiscal austerity means San Francisco is not a poor enough county to qualify for federal funds.
"Class warfare" is spending more money on incarceration than education.
"Class warfare", in short, is what people of the upper classes visit upon my students.
