Marie Corfield was frustrated by Governor Christie's unrelenting attacks on teachers and their unions. She decided to speak her mind at a Republican filled town hall meeting at Raritan Township in 2010. She said what she had to say. Listen to how Governor Christie responds in a condescending and aggressive way below (that's his style apparently - classy and professional, if you ask me.).
In the longer clip, it appears that Christie demolishes Corfield. But for people like Corfield and supporters of public education the issues are more nuanced. As explained in this NYT article, public union leaders all over the country have often bargained with rank and file members to forgo pay raises in exchange for enhanced benefits (i.e., higher pension contributions, a better health care plan, etc., etc.). So when Christie asks teachers to contribute more to their pension fund, what he's really asking is teachers to take a pay cut in order to pay for the state's financial mismanagement.
If Ford Motor Company signs a contract with, let's say, Rental Car Company X to deliver mid-sized sedans at $15,0000 a year for the next 5 years, and then three years into the contract, Ford says, "we're not doing so well. We need to raise the cost of the car to, uh, $17,000." What the hell is Rental Car Company X to do? They didn't mismanage the funds! Ford did. But in this case, it's even worse. Here, Christie and his allies are asking public employees to sacrifice for the following reasons: (a) their lack of foresight, (b) their unwillingness to raise taxes, (c) and their inability to manage a budget in tough times. In addition, public employees, on average, make less than people with the same education levels in the private sector.
