I felt that the biggest frustration the teachers had about their job, were the lack of respect they were receiving. They put so much time and money and effort into their jobs, but many were not receiving the credit they deserved. They were mistreated by their student, parents, and also at times, their employers.
I think one way for teaching conditions to improve without causing an increase in money is to be more involved with the student's parents. Because once you have the support of the parents, it makes teaching the kids more enjoyable.
