Yeah, that's only cuz it was Teacher Appreciation Week earlier in the month. She's complaining that she's undercompensated for her work, and he's telling her, so quit the job! Rather than discussing rationally whether or not her compensation is fair.
This kind of fuck-you attitude to hard-working and well-qualified civil servants can't bring any long-term benefit to anyone. It kills any willingness to compromise on the part of the teachers' union and it encourages school boards to hold the line on their side.
It's a perfect example of the class war, though - - the rich don't give a shit about public school teachers, because their kids are all in private schools anyway. They can afford "the best" for their kids' futures, they bought it and paid for it, so now fuck the rest of the community, fuck their kids and fuck their kids' futures. Christie, the Republican, represents the rich and he sure as hell ain't gonna tax them for educating the children of the non-rich in the public schools. Level playing field? Fuck dat!
