There's a big difference between public and private sectors here, with teaching being a good example. Sure, hiring the best dishwasher in the world isn't worth it, because you won't lose much if anything by getting some random kid to do it and paying minimum wage. But teaching isn't like that: they're not all the same. Hiring a great teacher gets you real, substantial gains over hiring a lousy teacher. There isn't a large, highly competitive pool of people entering the profession and fighting for jobs because teaching jobs don't pay well. And they don't pay well because salaries are constrained by government budgets. If we decided we wanted much better teachers, we could make more money available. That money would attract stronger candidates to the profession and get us better teachers. And those better teachers, replacing bad teachers, would make a real, tangible difference to the country. But we don't value teachers, so we don't make the money available.
Great theory. Try replacing underperforming teachers and see how the union responds. Secondly, exactly how do you determine who is underperforming?
I personally know several teachers right now with 20+ years of experience and they're counting the days until they can get out. Why? Because dealing with the kids, the parents and the administrators has become unbearable. Don't get me wrong. They love teaching, especially to kids who are interested in learning. They can't stand the disruptive, disrespectful and un-disciplinable (new word) students, disinterested or threatening parents and administrators who are more worried about covering their own butts rather than supporting their teachers.
I'm also not sure I buy this whole "teachers are the problem" notion. At this point in time, the internet has given our society access to more information than at any time in history.... basically for free. I haven't checked recently, but you used to be able to take college courses from some pretty respected universities online for free.
To me the question is, why aren't people interested in learning? It may very well be that the proliferation of information is causing people to either take it for granted (It's out there and I'll get around to learning about it sometime), or they don't know what to learn (what's important to know vs what's not), or they're just not interested.
I just spoke with one teacher nearing retirement yesterday who thinks teachers may be largely obsolete in 10 years. Her speculation is that the school systems will have their curriculum on video and the kids will just sit and watch. They may not even have to go to school. Just stay home. Watch and take standardized tests online. Nobody really cares if they learn or not. Just go through the process. Its more efficient and requires less resources (teachers, facilities, busses, etc)
This is way off topic so I'm gonna stop...
