Teacher's salary by subject area

I read, Teacher's salary by subject area by PEGuys (http://shifthappens.wikispaces.com/share/view/49335946). Wow, just wow. Governor Christie wants to pay teachers based on what subject they teach. Who decides which subject is better and worth more? All teachers are important and each child responds to each subject differently. Just because he thinks something is more important does not mean it is. A future doctor might find math and science important, but a future pilot might find just math important, and a future director might find art more important. Teachers get bum pay as it is, they should not take a pay cut because someone with no concept of teaching children thinks their subject is less important.
