Perhaps this is a good reason for a stronger social safety net. In other words, while on the one hand it is important to eliminate jobs that produce zero or negative value, or even ones that offer value lower than their total economic costs (which includes opportunity costs--ie children who learn more effectively by another teacher, or on their own), on the other hand it is very difficult to tell people they should be losing their job. One way to fix that is perhaps to entitle everyone to basic needs.
