All government pay, including the teachers and other unions should have the limit of their pay and benefits NOT EXCEED the average pay and benefits of the same work found in the private sector.
In other words, major reductions in salaries all around.
The government (all levels) should not be running the schools. All schools, K-12, colleges, universities...should be in the private sector, with education companies running them. This would automatically provide better choices, competition, higher quality, and reduced expense.
