Blogger Duncan Black thinks these figures indicate that Americans should stop cutting public school teachers’ wages and benefits, reducing their job security and making them scapegoats for all the ills of society.
But according to the neo-liberal philosophy that prevails in U.S. industry, the decline in the number of teachers is a good thing, not a bad thing.
A neo-liberal would tell you that fewer teachers with lower salaries teaching larger classes is by definition an increase in productivity (but that the best way to achieve this is through privatization).
Note: I am being ironic. I am not an advocate of neo-liberalism. My 40 years experience on newspapers tells me it is necessary to add this note.
