Sure some changes are minute and will take years if not generations to filter through but look at the changes to our education system!
Very simply put.
The very system under which todays a future generations will be provided with a grounding for life and at its end, hopefully, a bunch of certificates which, again hopefully, will ensure a position with an employer. The system of the 3 R's (Reading, Writing and Arithmetic, no, I do not get it either!), the very base level of our children's education has remained unchanged for years, centuries even. This culminated in a set of exams which if done at a sufficient levl gained status and credibility with employers.
Over time this system, which worked fine, was slowly changed until the mid 70's which thing settled down once more and both children and employers knew were they stood. Now, over the last 10 years or so of the current incumbent Labour government this status quo has slowly but surely been eroded with slight change after slight change. Until we reached a state where seemingly the basic premise of the 3R's are no longer relevant and the end certificates/qualifications are meaningless as to the child's skills.
I feel certain these changes are made, not for the benefit of our children's education but are changes for changes sake. I.E. They make the changes because they can.
