It's The Teachers Fault, Right?

Instead of blaming teachers and public schools for the growing wealth gap and the shrinking of the middle class, how about looking at the impact of:

The closing of factories and outsourcing of jobs
Low wages and stagnant salaries
Rising student and consumer debt
The drug war
The massive imprisonment of non violent offenders
Gentrification
Warehousing of abandoned properties
Racial profiling and Broken Windows Policing.
Tax relief for the very wealthy coupled with rising taxes for the middle class

Teachers are responsible for all those policy decisions and economic trends, right?
