"I can't believe teachers are denying there is a problem with how things are now. How bad do things have to get before they will hold their hands up and admit culpability?"
What are you waffling on about?
Since the dawn of the human age, people have been whining about the so-called golden eras of the past when all children were silent, polite, perfect geniuses who could spell perfectly and calculate all mathematical problems without fault.
There are Roman texts where the authors complain about the "youth of today" who seem to be so much ruder and badly educated than they remember being at their age.
Things aren't bad now. Not unless you read the Daily Mail and believe their lies. Quite the contrary in fact. Children have an incredible array of skills now, children who perhaps would have been neglected before. We have a range of tradesmen in my family in the older generations and many of them can't read or write to the degree that my class can now. Thank goodness things have changed for the better.
I'd say the biggest problem with the current education system is the overwhelming burden of parenting that we are supposed to accept as part of our job. Children can't wipe their own arse? Don't worry, that's what the teachers are there to teach them to do! Children eating a Mars Bar as their lunch? Don't worry, they need the energy.
